How to Convert Comma Separated String into an Array in JavaScript

Topic: JavaScript / jQueryPrev|Next

Answer: Use the split() Method

You can use the JavaScript split() method to split a string using a specific separator such as comma (,), space, etc. If separator is an empty string, the string is converted to an array of characters.

The following example demonstrates how to convert a comma separated string of person name into an array and retrieve the individual name using JavaScript.

<script>
var names = 'Harry,John,Clark,Peter,Rohn,Alice';
var nameArr = names.split(',');
console.log(nameArr);
    
// Accessing individual values
alert(nameArr[0]); // Outputs: Harry
alert(nameArr[1]); // Outputs: John
alert(nameArr[nameArr.length - 1]); // Outputs: Alice
    
var str = 'Hello World!';
var chars = str.split('');
console.log();
    
// Accessing individual values
alert(chars[0]); // Outputs: H
alert(chars[1]); // Outputs: e
alert(chars[chars.length - 1]); // Outputs: !
</script>
