Split Method in Javascript(JS) — with Examples

Hey everyone, in this article we will understand the most essential method, the split method in Javascript.

The split() method allows you to split a string into an array of substrings based on a specified separator. The original string remains unchanged, and the resulting substrings are stored in an array.

Let’s explore the syntax, usage, and examples of the split method in JavaScript following below:

Syntax of the Split Method

Here’s the syntax of the split() method:

string.split(separator, limit);

Separator: This parameter specifies the character or regular expression used to split the string. If the separator is not provided, the entire string becomes a single array element. An empty string (“”) as the separator will split the string into individual characters.

Limit (Optional): The limit parameter defines the maximum number of splits to be found in the string. If the string exceeds the limit, it won’t be included in the resulting array.

Now let’s look at some examples to understand how the split() method works:

1. Splitting with a Single Character Separator

You can split a string based on any character or sequence of characters. For instance:

const text = "apple,banana,orange,grape";
const fruits = text.split(',');

console.log(fruits); // Output: ["apple", "banana", "orange", "grape"]

2. Splitting a String into Individual Characters

If you want to split into an individual character then you can pass an empty string as the separator.

const sentence = "Javascript";
const characters = sentence.split('');

// Output:
// ["J", "a", "v", "a" ,"s", "c", "r", "i", "p", "t"]

3. Limiting the Number of Splits

You can limit the number of splits performed on a string by specifying the limit parameter.

const text = "apple,banana,orange,grape";
const limitedFruits = text.split(',', 2);

console.log(limitedFruits); // Output: ["apple", "banana"]

4. Splitting with a Regular Expression Separator

If you want to split the string with a regular expression then pass the expression in the method.

const text = "apple banana,orange grape";
const words = text.split(/\s+/); // Split by one or more spaces

console.log(words); // Output: ["apple", "banana,orange", "grape"]

5. Splitting on Newlines

const multilineText = "Line 1\nLine 2\nLine 3";
const lines = multilineText.split('\n');

// Output:
// ["Line 1", "Line 2", "Line 3"]

6. Splitting Strings with Multiple Delimiters


const data = "John:Doe:25";
const parts = data.split(/:/);

console.log(parts); // Output: ["John", "Doe", "25"]


let str = 'Apples,Oranges;Bananas-Grapes';
let array = str.split(/,|;|-/);

// Output: ["Apples", "Oranges", "Bananas", "Grapes"]

In this last example, the regular expression /:/ or /,|;|-/ is used to split the string at each colon. This results in an array containing separate parts of the input data.

🗒️ Note: Remember that the split() method returns an array of substrings. You can access individual elements of the resulting array using array indexing (e.g., fruits[0] to access the first element).

So, that’s all about the split method in JS. With the split method, you have the flexibility to extract meaningful information from strings in JavaScript.
