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:
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: WelcomeGeeksforGeeks
The JavaScript Array toString() Method returns the string representation of the array elements
Syntax:
arr.toString()
Example:
Javascript
function func() {
let arr = [ "Geeks" , "for" , "Geeks" ];
let str = arr.toString();
console.log(str);
}
func();
