JavaScript How to Get Character Array from String? (original) (raw)

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?

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.
