JavaScript - How to Get Character Array from String?

Last Updated : 09 Jan, 2025

Here are the various methods to get character array from a string in JavaScript.

1. Using String split() Method

The split() Method is used to split the given string into an array of strings by separating it into substrings using a specified separator provided in the argument.

JavaScript

let s = "GeeksforGeeks"; let a = s.split(""); console.log(a);

Output

[   'G', 'e', 'e', 'k',   's', 'f', 'o', 'r',   'G', 'e', 'e', 'k',   's' ]

2. Using JavaScript Spread Operator

The Spread operator allows an iterable to expand in place. In the case of a string, it breaks string to character and we capture all the characters of a string in an array.

JavaScript

let s = "GeeksforGeeks"; console.log([...s]);

Output

[   'G', 'e', 'e', 'k',   's', 'f', 'o', 'r',   'G', 'e', 'e', 'k',   's' ]

3. Using Array.from() Method

The Array.from() method creates a new array instance from a given array. In case of string, every alphabet of the string is converted to an element of the new array instance, and in the case of integer values, a new array instance simply takes the elements of the given array.

JavaScript

let s = "GeeksforGeeks"; let a = Array.from(s); console.log(a);

Output

[   'G', 'e', 'e', 'k',   's', 'f', 'o', 'r',   'G', 'e', 'e', 'k',   's' ]

4. Using for ... of Loop

The for...of loop provides manual control over iteration to create a character array.

JavaScript

const s = 'GeeksforGeeks'; const a = []; for (const s1 of s) { a.push(s1); } console.log(a);

Output

[   'G', 'e', 'e', 'k',   's', 'f', 'o', 'r',   'G', 'e', 'e', 'k',   's' ]

Which Approach Should You Use?

Approach	When to Use
Using String.split()	Best for simplicity and readability.
Using Spread Operator	Ideal for concise ES6+ code.
Using Array.from()	Suitable when you need additional transformations during array creation.
Using for..of Loop	Useful when custom processing is required for each character.

The String.split() and Spread Operator methods are the most commonly used for their simplicity and readability. Use Array.from() or for...of when additional customization or transformations are required.
