How to create a string by joining the elements of an array in JavaScript ?
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. 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.
