Given an array containing array elements and here we will join all the array elements to make a single string. To join the array elements we use arr.join() method.
There are two methods by which we can create a string by joining the elements of an array:
- Using arr.join() Method
- Using arr.toString() Method
Method 1: Using arr.join() Method
This method is used to join the elements of an array into a string. The elements of the string will be separated by a specified separator and its default value is a comma(,).
Syntax:
array.join(separator)
Example: In this case, we use an empty separator i.e. array.join(“”) to join the array elements.
Javascript
let str = [ "Welcome" , "Geeks" , "for" , "Geeks" ]; console.log( "Joined String: " + str.join( "" )); |
Joined String: Welcomeneveropen
Method 2: Using arr.toString() Method
The JavaScript Array toString() Method returns the string representation of the array elements
Syntax:
arr.toString()
Example:
Javascript
// JavaScript to illustrate toString() method function func() { // Original array let arr = [ "Geeks" , "for" , "Geeks" ]; // Creating a string let str = arr.toString(); console.log(str); } func(); |
Geeks,for,Geeks
