The string.split() method is an inbuilt method in JavaScript that is used to split the string by the separator and get an array of words or characters, including punctuation marks. The split() method can limit words or characters in the array, specify words or punctuation marks in the split() method, and remove words and phrases from the string.

Syntax of JavaScript string.split() Method

referenceString.split(separator);
referenceString.split(separator, limit);

Parameters

Return

It returns an array of strings based on the separator and limit parameters.

Example Code: Use the string.split() Method to Create Unique Substrings

let str = 'Hello World! Welcome to everyone.';
let regE = str.split(" ");
let arr = str.split("World! Welcome to");
console.log(regE);
console.log(arr);

Output:

Hello,World!,Welcome,to,everyone.
Hello , everyone.

In the example above, we have passed separator with different values to return the substrings.

Example Code: Use the string.split() Method to Limit the Characters or Words for a New Array

let str = 'Hello World!';
let arr = str.split(" ", 1);
let ref = str.split("", 5);
console.log(arr);
console.log(ref);

Output:

'Hello'
'H', 'e', 'l', 'l', 'o'

In the above example, We passed the limit parameter with the separator parameter, which limits the size of the array of substrings returned by the string.split() method.
