Introduction to C++ any() Function

Bitset is one of the important class in the C++ library that helps to emulate strings or numbers in the form of a sequence of bits stored like an array where each of the bits is stored at consecutive positions in the array. Since the storage dataset used is an array, each bit can be referenced by a particular index that helps in fast access of elements. Any() method is one of the methods provided in Bitset Class to find if any of the bit present in the array is set that is its value is ‘1’. If none of the bit is set false is returned.

Syntax:

Before C++11: bool any() const;

Since C++11: bool any() const noexcept;

This method requires no parameters to be passed while calling. Only the reference to one of the objects of Bitset class calls this method for the bitset representation object is holding.

Bool: Determines that the return type for this method is a Boolean, that is either true in case any one of the bit is set otherwise false.

Const: restricts any changes to this method by any of its child classes.

After C++11 this method does not throw any exception, can be inferred using noexcept keyword mentioned in its declaration.

How any() Function Works in C++?

A bitset helps to emulate an array of bool where each bit is stored in such a way to use memory efficiently as memory consumed to store a bitset is far less than the storage of Boolean array or vector. Thus it can be inferred the information stored using bitset is stored in a compressed manner, thus helps in enhancing the performance of the array and vector operations on it. The only limitation of using bitset is the size of the array needs to be declared at compile time.

1. Each bit in bitset array can easily be accessed using indexes for eg, obj[3] points to the element stored at index 3 in the bitset from right side.

2. Bitset also gives constructor to get the bitset representation of given string and numbers. Thus one can easily use this class to store the information. It provides various methods to perform operations on the bits such as :-

Count

All

Any

Test

Set

3. When Any() method is triggered for a bitset object, the compiler traverse the whole array of bitset from 0 to N index, where N is declared at compile-time, and checks if the bit is set i.e the value of the bit at that index is 1. If yes it breaks the loop and returns true Boolean otherwise False Boolean. Any() method working is same as loop given below:-

for(int i=0;i<bitsObj.size();i++){ if(bitsObj.test(i)){ return true; break; } else{ return false; } } Advantage of any() Function in C++

All the bitwise operations on bitset can be performed without any type of conversion or casting, which helps enhance the performance and efficiency.

Examples to Implement of C++ any() Function Example #1

Let us consider one simple example to understand how any function in bitset works.

Code :

using namespace std; int main() { bool result1 = obj1.any(); if (result1) cout << obj1 << ” has one of its bits set” << endl; else cout <<  ” None of the bits is set in “<< obj1 << endl; bool result2 = obj2.any(); if (result2) cout << obj2 << “  has one of its bits set” << endl; else cout << “None of the bits is set in ” << obj2 << endl; return 0; }

Output :

Explanation: Here since obj1 10010 has a bit set at 1 and 4th index thus any method returns true for it. But in case of obj2 000000 has none of its bits as set returns false.

Example #2

Code :

using namespace std; #define M 32 int main() { cout << “Bitset representation of uninitialised obj1 is ” <<obj1 << endl; cout << “Bitset representation of 16 is ” <<obj2 << endl; cout << “Bitset representation of “00010” is ” <<obj3 << endl; cout << endl; bitarr[3] = 1; bitarr[2] = bitarr[3]; cout << “Bitset representation of array with 2nd 3rd bbits set is “<< bitarr << endl; cout << “Lets check if any of the bit is set in above 4 bitset representations: “; if( obj1.any()) cout<< “obj1: ” <<“TRUE”<<endl ;else cout << “FALSE” <<endl; if( obj2.any()) cout<< “obj2: ” <<“TRUE”<<endl ;else cout <<“FALSE” <<endl; if( obj3.any()) cout<< “obj3: ” <<“TRUE” <<endl;else cout<<  “FALSE” <<endl; if( bitarr.any()) cout<< “bitarr: ” <<“TRUE”<<endl; else  cout<< “FALSE” <<endl; cout << endl; return 0; }

Output:

Explanation: In the above-given example, M defines the length of the bitset array for all the given bitset objects. Since obj1 is uninitialized thus its value is by default initialized to 0. Second object obj2 is a number -16 that is converted using bitset constructor to its bitset representation. The third object is in the form of bits 00010 and has bit set at index 1. And the fourth index is a bitset array uninitialized, thus stores 0 value in the start but its 2nd and 3rd bit is set at runtime. Any() method is used to find if any of the bit in the given objects is set or not.

Conclusion

Bitset representation plays an important role as it helps to work with bits representation of string or numbers. And Since the machine understands the language of “0” and “1”, working with this representation improves the performance. Any() is one of the methods provided in this class to find if any of the bit is set in the given bitset object.

Examples Of The Operator=() Function In C++

Introduction to C++ operator=()

Web development, programming languages, Software testing & others

So when the assignment operator is overloaded, the assignment operator should be performed on the user-defined data types as well, so all values of one object (user-defined data types) can be copied to another object.

Syntax 

Below is the syntax mentioned:

return_type : : operator =(Parameter_list ) { }

An operator is an operator function where the operator is a keyword that will be there for all operators overload and = is an assignment operator being overloaded.

Working and Examples of the Operator=() function in C++

Next, we write the C++ code to understand the Operator=() function working more clearly with the following example where we use Operator=() function to copy one object to another object, as below –

Example #1

Code:

using namespace std; class Employee { public: int salary; Employee( int sal ) { salary = sal; } Employee operator =(Employee n) { Employee temp = n.salary; return temp; } }; int main() { Employee e1( 20000 ); Employee e2( 25000 ); Employee e3 = e1; cout<< e3.salary; return 0; }

Output:

As in the above code, the Employee operator =(Employee n ); function is defined for an assignment operator overload, as here this function accepted the Employee class object as a parameter, and it returns accepted object salary that is what assign or copy to another object when used assignment operator as in code Employee e3 = e1; Once compiler encounter e3 = e1; statement it calls to the operator =(Employee n ); defined function as e3.operator =(e1). Here e1 object is passed as a parameter, and e3 is the object on which the assignment operator function is called, so e1.salary is assigned or copied to the e3 object.

Next, we rewrite the above C++ code to see what happens if we do not define the Operator =() function in class to copy one object to another object, as below –

Example #2

using namespace std; class Employee { public: int salary; Employee( int sal ) { salary = sal; } }; int main() { Employee e1( 20000 ); Employee e2( 25000 ); Employee e3 = e1; cout<< e3.salary; return 0; }

Output:

As in the above code the Employee operator =(Employee n); function is not defined for an assignment operator to be overloaded, but object e1 is copied to e3 as we got the same output 20000. So the assignment operator is overloaded for user-defined objects, whereas other binary operators, by default not overloaded like ‘+,’ ‘-, ‘‘*’ etc.

Next, we rewrite the above c++ code to see what happens if we do not define the Operator +() function in class to perform the addition of object, as below –

Example #3

Code:

using namespace std; class Employee { public: int salary; Employee( int sal ) { salary = sal; } }; int main() { Employee e1( 20000 ); Employee e2( 25000 ); Employee e3 = e1 + e2; cout<< e3.salary; return 0; }

Once we compile the above code we get the below error –

Next, we rewrite the above C++ code to overload the Operator=() function where it copies one object to another object with some operation, as below –

Example #4

Code:

using namespace std; class Employee { public: int salary; Employee( int sal ) { salary = sal; } void operator =(Employee n) { salary = n.salary + 10000; } }; int main() { Employee e1( 20000 ); Employee e2( 25000 ); e2 = e1; cout<< e2.salary; return 0; }

Output:

As in the above code, the Employee operator =(Employee n); function is defined for an assignment operator overload, as here this function accepts the Employee class object as a parameter, and it updates the salary of the calling object by the salary of the passed object with the addition of 1000. So when an assignment operator is used as in the above code, Employee e3 = e1; the e3 salary is updated or copied by e1 object salary plus 10000. Therefore the output is 30000, not just 20000.

Conclusion

Operator=( ) overload an assignment Operator in C++, which can be used to redefine the assignment operators to perform the operation on the user-defined data type.

How Function Works In Scala With Examples

Definition of Scala Function

As the name suggests, Scala Function means a piece of code supposed to do a function. Like any other programming language scala, Function works in the same way. The function is nothing but a way to writing our logic in a separate part, or we can say a function is a group of statements that are responsible for performing some specific task. The function can be used where we have the same logic or repetitive code, so instead of writing the code again and again, we can create one function and call that from everywhere. Scala function is also responsible for performing a specific task.

How to Define Functions in Scala? defname_of_function ([parametre_list]) : [return_type] = { }

Scala Function contained 6 parts while defining; let’s discuss them one by one.

def: It is a keyword that is available in scala. If you want to define any function, we have to use this keyword at the beginning.

name_of_function: This is the user-defined name of the function. It should be similar to the logic or task that the function is going to execute while calling. Also, it should be in a camel-case (lower).

return_type: return type means what we are expecting from the function in return after executing. It can be anything, but it is optional. In java, the default return type is void, and in scale, it is Unit if we do not specify.

parametre_list: This stands for what we are providing to our function while calling. We have to specify the data type of the parameters as well while declaring inside the square brackets []. We will see them into the practice syntax below.

 =: This can be used with the return type component. It specifies, if the = is there, it means our function is going to return some value. If not, then no value we want. It is like a default return type function.

function logic: Inside this, we write the whole logic that we want to perform on the calling of function. We can also call the different functions inside this function. Remember body should be enclosed with the {} curly braces.

defcalculateSum ([a:Int, b: Int]) : Int = { return a + b; }

This way, we can define it.

How does Function work in Scala?

The function is used to perform the task. To use any function, we need to call it. Scala provides us with different ways to call a function, i.e. we can call them directly or by using the class instance.

[instance].name_of_function

or

function(list_parameter)

In scala, we have two types of functions like any other programming language.

Parameterized functions: In this type of function, we pass the list of parameters.

Non-Parameterized functions: In this type of function, we do not pass any parameters to function. That will be empty. Also, we can pass any user-defined value as a parameter also.

Let’s take one example to understand its working;

object Main extends App{ calculateSum(10, 20) defcalculateSum(a : Int, b : Int){ var result = a + b ; println("Result is  :: "+ result) } }

Above we have defined one function name calculateSum, and it is taking two variables, a and b. Both are of the Integer type. Inside the function body, we have written the logic that we want to perform. We are adding these two values, a and b, holding the value into the third variable named result. After that, we are just printing the value that we obtained. But now we have to call this function, so in the above line, we are calling the function b its name and parameter specified. The number of Parameters we passed and the number defined in the function signature should be the same; otherwise, it will give a compile-time error.

Examples of Scala Function

Examples of (simple function, parameterized function, etc.).

Example #1

This example shows the use of functions without parameters.

object Main extends App{ simpleFunction() defsimpleFunction(){ println("This is simple function") println( "without parameter. ") } }

Output:

Example #2

Code:

object Main extends App{ sum(20 , 50, 100) defsum(x: Int, y : Int, z: Int){ println("This is parameter function") var result = x + y +z println("result obtained is  :::"  +result) } }

Output:

Example #3

In this example, we are making a mixed parameter list of a function. This takes integer and string as well.

Code:

object Main extends App{ mixedFunction(20 , 50, 100, "Ajay", "Indore") defmixedFunction(x: Int, y : Int, z: Int, name: String, address: String){ println("This is parameter function") var result = x + y +z println("result obtained is  :::"  +result) println("Employee name  :: " + name) println("Employee address  :: " + address) } }

Example #4

In this example, we are taking a user-defined object and printing its value. We can take any value as a parameter.

Code:

object Main extends App{ var emp1 = new Employee("Amita", 20, 30, "Indore") employeeInfo(emp1) defemployeeInfo(emp : Employee){ println("In this we are taking one user defined parameter.") println("Passing a user value ::") } } class Employee(name: String, Id:Int, Age: Int, address: String){ }

Output:

Conclusion

Functions are used to avoid the redundant code or repetitive code. It makes our code looks simple and more understandable. Also, we can easily debug our code and identified the error, if any. These Scala functions are the same as any other programming language. Keep in mind the return type and parameter list or signature of the function while working with them.

Learn How Does Es6 Proxy Works With Examples?

Introduction to ES6 Proxy

The ES6 proxy is between the code and an object using as an ES6 proxies site, but we can use a proxy to do meta-programming activities like intercepting a call to examine or change the properties of an object with certain properties or methods called as the functions which are defined as the handler with certain properties or methods are called and functions defined in the handler offer access to the target.

Start Your Free Software Development Course

What is an ES6 proxy?

The ES6 proxy is placed between the middle of the code and an object. We can use a proxy to do meta-programming activities like intercepting a call to examine or change the properties of an object. When it comes to ES6 proxies, it has followed the certain nomenclature is used like a target. The proxy will virtualize the original object.

How to use Proxies?

The Proxies are generally meant by the specific computing terms like intermediaries between the objects with which we can communicate. Then the proxy server is meant by the device that sits between the web browser like (Chrome, Firefox, Safari, Edge, and so on) also the webserver like (Apache, Nginx, IIS, and so on) whereas the webpage is to be stored in the cookies and histories. The client requests and the response answers can be modified by using the proxy server. It can be boosted and efficient by caching frequently visited items and providing them to numerous users.

It has a number of proxy trap types like mainly get and set methods are the most useful traps. The other traps like proxy and supplement proxy handler codes. A Proxy is an object that wraps around another object (target) and intercepts the target object’s basic operations. Property search, assignment, enumeration, and function invocations are examples of basic operations.

How does ES6 Proxy work?

Generally, the ES6 module is a container for a group of JavaScript codes that can be related to one another. Especially the module’s variables and functions should be exported so that they can be accessible from the other files. However, in ES6 scripts, the modules can only be used in the strict mode. This means that the variables and functions are declared in a module that cannot be globally accessible. Mainly it focuses on the target and handler; the target is the original object that can be used for proxy wanted, and the handler is the kind of the object that can be defined the specified operations will be more intercepted and redefined the intercepted operations.

Target:

The proxy will virtualize the original object. And this could be a source JavaScript object and like the jQuery library, native objects, like arrays, or even other proxies which may be used on the servers.

Handler:

An object that can be used for to implement the proxy’s behavior. Now we’ll make a handler object that will intercept all get operations.

Traps:

Examples of ES6 Proxy

Different examples are mentioned below:

Example #1

Code:

function mthd1(x, y) { var a = Object.getOwnPropertyDescriptor( y.prototype, ‘constructor’ ); y.prototype = Object.create(x.prototype); var handler = { construct: function(target, args) { var obj = Object.create(y.prototype); this.apply(target, obj, args); return obj; }, apply: function(target, c, args) { x.apply(c, args); y.apply(c, args); } }; var prx = new Proxy(y, handler); a.value = prx; Object.defineProperty(y.prototype, ‘constructor’, a); return prx; } var v = function(n) { this.n = n; }; var w = mthd1(v, function(n, sno) { this.sno = sno; }); w.prototype.cty = ‘T’; var ins = new w(‘ins’, 32); document.getElementById(“one”).innerHTML = ins.cty; document.getElementById(“one”).innerHTML = ins.n; document.getElementById(“one”).innerHTML = ins.sno; let trg = {}; let prx = new Proxy(trg, {}); prx.tst = 3; alert(trg.tst); alert(prx.tst); for(let k in prx) alert(k);

Output:

In the above example, we used the Proxy object and the handler concept to create and handle user datas. It can be mainly classified to the object wrapping and intercept operations like reading and writing properties and other features. Basically, it handles the object them on its own; it allows for to transparently objects handled them.

Example #2

const hnd = { get: function(a, b) { return b in a ? a[b] : 45; } }; const obje = new Proxy({}, hnd); obje.x = 1; obje.y = undefined; document.getElementById(“one”).innerHTML = obje.x, obje.y; document.getElementById(“one”).innerHTML  = ‘z’ in obje, obje.z; const target = {}; const ins = new Proxy(target, {}); ins.e = 73; document.getElementById(“one”).innerHTML = target.e;

Output:

In the above example, we used the same Proxy object with all the html dom elements in the stack. The default value is whenever the property name is not in the object creation. It will be used as the get() handler method. Mainly, we are using native import JavaScript objects for which the proxy will be forwarded to all the user operations that are applied to it on the programming logic, including both UI and backend validations. And also, please note that while we use any looping conditional statements, the javascript objects work as a no-op, and it does not mean the native browser objects like DOM Elements.

New Proxy to intercept the operation

We can use a proxy for to intercept the multiple user operations mainly used as the following methods like,

get (getting property values)

apply (calling a function)

But it does not perform any single operation for calling the methods that can be intercepted. This is why method calls are split into two steps: first, we can use get to obtain a function, and then it can apply it for specific operations.

Conclusion

A proxy object which “traps” for invocations and users performed the multiple operations made to its target object. And which it can be subsequently passed through the no-operations and handled more elegantly. It can erect an impenetrable barrier around the target object, redirecting to all the operations specified mapping to the handler.

How Interpolate Function Works In Pandas?

Introduction to Pandas Interpolate

Web development, programming languages, Software testing & others

Syntax and Parameters:

Pandas.interpolate(axis=0, method='linear', inplace=False,  limit=None, limit_area=None, limit_direction='forward', downcast=None, **kwargs)

Where,

Axis represents the rows and columns; if it is 0, then it is for columns, and if it is assigned to 1, it represents rows.

Limit represents the most extreme number of successive NaNs to fill. Must be more noteworthy than 0.

Limit direction defines whether the limit is in a forward or backward direction, and by default, it is assigned to the forward value.

Limit area represents None (default) no fill limitation. inside Only fill, NaNs encompassed by legitimate qualities (add). outside Only fill NaNs outside substantial qualities (extrapolate). On the off chance that cutoff is determined, sequential NaNs will be filled toward this path.

Inplace means to brief the ndarray or the nd dataframe.

Downcast means to assign all the data types.

How does Interpolate Function work in Pandas?

Now we see various examples of how the interpolate function works in Pandas.

Example #1: Using in Linear Method

Code:

import pandas as pd df = pd.DataFrame({"S":[11, 3, 6, None, 2], "P":[None, 5, 67, 4, None], "A":[25, 17, None, 1, 9], "N":[13, 7, None, None, 8]}) df.interpolate(method ='linear', limit_direction ='forward') print(df.interpolate(method ='linear', limit_direction ='forward') )

Output:

In the above program, we first import the panda’s library as pd and then create the dataframe. After creating the dataframe, we assign values to the dataframe and use the interpolate function to define the linear values in the forward direction. The program is implemented, and the output is as shown in the above snapshot.

Example #2: Using in Backward Direction

Code:

import pandas as pd df = pd.DataFrame({"S":[11, 3, 6, None, 2], "P":[None, 5, 67, 4, None], "A":[25, 17, None, 1, 9], "N":[13, 7, None, None, 8]}) df.interpolate(method ='linear', limit_direction ='backward', limit = 1) print(df.interpolate(method ='linear', limit_direction ='backward', limit = 1) )

Output:

In the above program, we first import the panda’s library as before and then create the dataframe. After creating the dataframe and assigning values, we use the interpolate() function in the backward direction, and it shows all the linear values in the backward direction, as shown in the above snapshot.

In the first place, we create a pandas information outline df0 with some test information. We make a counterfeit informational index containing two houses and utilize a transgression, and a cos capacity to create some sensor read information for many dates. To create the missing qualities, we haphazardly drop half of the sections. A transgression and a cos work, both with a lot of missing information focus. Recall that it is critical to pick a sufficient introduction technique for each errand. For instance, on the off chance that you have to add information to figure out the climate, at that point, you cannot introduce the climate of today utilizing the climate of tomorrow since it is as yet obscure.

To insert the information, we can utilize the group by()- work followed by resample(). In any case, first, we have to change over the read dates to DateTime organization and set them as the file of our data frame. Since we must introduce each house independently, we must gather our information by ‘house’ before utilizing the resample() work with the alternative ‘D’ to resample the information to a day-by-day recurrence. In the event that we need to mean interject the missing qualities, we have to do this in two stages. To start with, we produce the basic information lattice by utilizing mean(). This produces the lattice with NaNs as qualities. A while later, we fill the NaNs with introduced esteems by calling the add() strategy on the read esteem segment.

Conclusion

Hence, I conclude by stating that anybody working with information realizes that genuine information is frequently sketchy, and tidying it takes up a lot of your time. One of the highlights I have learned how to acknowledge especially is the straightforward method of adding (or in-occupying) time arrangement information, which Pandas gives.

How Settimeout Function Works In Node.js?

Introduction to chúng tôi timestamp

A timestamp is the numerical conversion of date and time value in an Integer like a number that is the time in milliseconds. Every technology and in every application, the most widely used functionality is the date object, which helps retrieve, share, save, and update the date values across the application. In NodeJS Timestamp, the Date and time fields come under the JavaScript Framework, where the Date Object of JavaScript is used without any external dependency and returns back time in milliseconds. In this topic, we are going to learn about chúng tôi timestamps.

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

Syntax

Get Current Timestamp Value in the millisecond

var dateTimeStamp = Date.now(); console.log(" Current Timestamp :: " + dateTimeStamp);

How setTimeout Function Works in Node.js?

In NodeJS, Timestamp objects consisting of Date and Time fields are provided by the JavaScript framework itself and need not be imported explicitly in NodeJS code. As soon as JavaScript executes the Date.now() method, it calculates the Total number of Milliseconds which have been passed since Jan 1, 1970, as it’s the UNIX timestamp and picks the system timezone as default timezone and returns timestamp in milliseconds. It has been observed that Date.now() is not compatible with IE 8 or any lower versions, and so you might have created a new Date object and call getTime method instead of calling Date.now(). The JavaScript Timezone comes with lots of inbuilt methods which can be used in applications using JavaScript Framework. Playing around with time and date values and utilizing these values in UI fields, storing in the database or comparing time or Date across the application is one of the most common use cases in any application.

Examples of chúng tôi timestamp

Given below are the examples of chúng tôi timestamp:

Example #1 – Get Current Timestamp Value in the millisecond

Code:

var dateTimeStamp = Date.now(); console.log(" Current Timestamp :: " + dateTimeStamp);

Output:

Example #2 – Get Time in milliseconds from the specified Timestamp

Code:

var dateTimeStamp = Date.now(); var dateObject = new Date(dateTimeStamp); var timeInMs = dateObject.getTime(); console.log("Date Time in milliseconds :: " + timeInMs);

Output:

Example #3 – Get Today’s Date Value from the specified Timestamp

Code:

var dateTimeStamp = Date.now(); var dateObject = new Date(dateTimeStamp); var dateFromTS = dateObject.getDate(); console.log("Today's Date Value :: " + dateFromTS);

Output – Today’s Date Value:: 11

Note: Date is returned as an integer ranging from 1-31 

Example #4 – Get Month Value from the specified Timestamp

Code:

var dateTimeStamp = Date.now(); var dateObject = new Date(dateTimeStamp); var monthFromTS = dateObject.getMonth() + 1; console.log("Month Value is :: " + monthFromTS);

Output – Month Value is:: 8

Note: Month is returned as an integer ranging from 0-11, where 0 is for January and 11 for December. Make sure to account for this while displaying or using Month value.

Example #5 – Get Today’s Year in 4 digit format from the specified Timestamp

Code:

var dateTimeStamp = Date.now(); var dateObject = new Date(dateTimeStamp); var yearFromTS = dateObject.getFullYear(); console.log("Year in 4 digit Value :: " + yearFromTS);

Output:

Note: Year Value is returned as a 4 digit Integer always

Example #6 – Get Timestamp in Seconds

Code:

var timeInMS = Date.now(); var timeInSeconds = Math.floor(timeInMS/1000) console.log("Timestamp in MS :: " + timeInMS); console.log("Timestamp in Seconds :: " + timeInSeconds);

Output:

Example #7 – Get-Date in DD-MM-YYYY format from the current timestamp

Code:

var dateTimeStamp = Date.now(); var dateObject = new Date(dateTimeStamp); var yearFromTS = dateObject.getFullYear(); var monthFromTS = dateObject.getMonth() + 1; var dateFromTS = dateObject.getDate(); console.log("Date in DD/MM/YYYY :: " + dateFromTS + "/" + monthFromTS + "/" + yearFromTS);

Output:

Example #8 – Get-Date in UTC from the current timestamp

Code:

var dateTimeStamp = 1597049017329; var dateObject = new Date(dateTimeStamp); var utcYearFromTS = dateObject.getUTCFullYear(); var utcMonthFromTS = dateObject.getUTCMonth() + 1; var utcDateFromTS = dateObject.getUTCDate(); var utcTimeFromTS = dateObject.getUTCHours(); var utcMinutesFromTS = dateObject.getUTCMinutes(); console.log("UTC Date in DD/MM/YYYY HH:MM  " + utcDateFromTS + "/" + utcMonthFromTS + "/" + utcYearFromTS + " " + utcTimeFromTS + "hrs : " + utcMinutesFromTS + "minutes");

Output:

Example #9 – Get Offset in Timezone from Specified Timestamp

Code:

var dateTimeStamp = Date.now(); var dateObject = new Date(dateTimeStamp); var timeZoneOffsetValue = dateObject.getTimezoneOffset(); console.log("Offset :: " + timeZoneOffsetValue);
