Hello reader's in this tutorial we are going to create a string from array. We will use array object method to join an array element into a string. The in-built join method will join the array elements into a string.

Syntax:-

var fruitArray = ['apple','peach','lemon','lime'];
var resultString = fruitArray.join('-'); // apple-peach-lemon-lime

The one optional parameter is taken by the array join method. To make a separate string use a delimiter, when the array joined in this case by using dash(-). All of the array elements concatenated when it returns a string.

The values converted into a equivalent string if the array contains anything other than strings.

Syntax:-

var numberArray = [1,2,3,4,5]; // array literal containing number elements
var resultString = numberArray.join('+'); // returns string with 1+2+3+4+5

By default the comma is inserted between array element if we don't give a delimiter parameter.

Syntax:-

var numberArray = [1,2,3,4,5];
var resultString = numberArray.join(); // returns string with 1,2,3,4,5

Hope, this tutorial will help you to create a string from array.
