The newline character is an important consideration when working with strings in JavaScript. Its purpose is to create a new line when printed. While 'n' is often assumed to be the universal newline character sequence in JavaScript, it's essential to understand that this may not hold true across all platforms.

Determining the Platform-Specific Newline Character in JavaScript

The platform-specific newline character can vary. To determine the correct newline character for the current environment, use the following code snippets:

• For Node.js:

const os = require('os');
const newline = os.EOL;

Copy after login
• For the browser:

const newline = document.createElement('textarea').value.substring(0, 1);

Copy after login

Example Implementations Using Different Newline Characters

Here are some examples that demonstrate the use of newline characters in JavaScript:



• Using 'n' in a string:

const message = "Hello\nWorld!";
console.log(message); // Output: Hello
// World!

Copy after login
• Using a platform-specific newline character:

const newline = os.EOL;
const message = `Hello${newline}World!`;
console.log(message); // Output: Hello
// World!

Copy after login
