How to Split a String into an Array of Characters in JavaScript

Use the split() Method

The JavaScript split() method is used to split a string using a specific separator string, for example, comma (,), space, etc. However, if the separator is an empty string (""), the string will be converted to an array of characters, as demonstrated in the following example:

<script>
// Sample string
var str = "Hello World!";
 
// Splitting the string
var chars = str.split("");
 
console.log(chars);
// Prints: ["H", "e", "l", "l", "o", " ", "W", "o", "r", "l", "d", "!"]
 
// Accessing individual character
alert(chars[0]); // Outputs: H
alert(chars[1]); // Outputs: e
alert(chars[2]); // Outputs: l
alert(chars[chars.length - 1]); // Outputs: !
</script>
