JavaScript - convert string with commas to array

In this article, we would like to show you how to convert string with commas to array in JavaScript.

In this example, we use split() method with comma (',') as separator to split string with commas into array of strings.

xxxxxxxxxx

var text = '1,2,3';

​

var array = text.split(',');

​

console.log(array); // [ '1', '2', '3' ]

In this example, we additionally use map() method to convert all elements from the splitted array into Number type.

xxxxxxxxxx

var text = '1,2,3';

​

var array = text.split(',').map(Number);

​

console.log(array); // [ 1, 2, 3 ]
