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("")); |
Output
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() methodfunction func() { // Original array let arr = ["Geeks", "for", "Geeks"]; // Creating a string let str = arr.toString(); console.log(str);}func(); |
Output
Geeks,for,Geeks
