Last Updated : 13 Oct, 2021

The os.EOL constant is an inbuilt application programming interface of the os module which is used to get end-of-line character or marker as specified by the operating system.Syntax:

os.EOL

Return Value: It returns the EOL (end-of-line marker) as specified by the operating system on which it is running. Below examples illustrate the use of os.EOL constant in Node.js:Example 1:

javascript `

// Node.js program to demonstrate the
// os.EOL constants

// Allocating os module const os = require('os');

// Printing os.EOL character(s) by // stringifying to JSON otherwise it // will simply print as end of line console.log(JSON.stringify(os.EOL));

`

Output:

"\r\n"

Example 2:

javascript `

// Node.js program to demonstrate the
// os.EOL constants

// Allocating os module const os = require('os');

// Printing os.EOL character(s) with string console.log("Paragraphs always contains EOL" + os.EOL + "EOL stands for end of line");

console.log("EOL varies from os to os" + os.EOL + "For windows it is \r\n" + os.EOL + "For POSIX it is \n" + os.EOL);

`

Output:

Paragraphs always contains EOL EOL stands for end of line EOL varies from os to os For windows it is \r\n For POSIX it is \n

Note: The above program will compile and run by using the node index.js command.Reference: https://nodejs.org/api/os.html#os_os_eol
