Split A String By Newline In JavaScript

How to Split a String by Newline in JavaScript

To split a string by newline in JavaScript, you can use the split() method combined with a regular expression string.split(/\r?\n/) this matches newline characters. Here’s an example:

let string = "Hello\nWorld\nThis is JavaScript";
let lines = string.split(/\r?\n/); // Splits by both Windows and Unix newlines
console.log(lines);
// Output: [ 'Hello', 'World', 'This is JavaScript' ]

This code splits the string by newline characters (\n or \r\n) and returns an array with each line as an element.

(/\r?\n/) is a regular expression that matches either \r\n (Windows-style) or \n (Unix-style) newline characters.

Follow the steps below to split a string by newline in JavaScript.

Steps:

1. Prepare the string: Create a string that contains newline characters. You can use the escape sequence \n to represent the newline.
2. Use the split() method: Use the split() method with the regular expression string.split(/\r?\n/) this matches newline characters to split the string into an array of lines.
3. Log the result: Output the result to the console using console.log() to verify the string is correctly split.
