Below examples illustrate the url.toJSON() method in Node.js:

Example 1:

// node program to demonstrate the
// url.toJSON() method in node.js

// Require an URL module
const url = require('url');

// Creating and initializing myURL variable
var urls = [
    new URL('https://www.geeksforgeeks.com'),
    new URL('https://www.google.com'),
    new URL('https://www.mygeeks.com')
];

// Display result
console.log(JSON.stringify(urls));

Output:

[
    "https://www.geeksforgeeks.org/",
    "https://www.google.com/",
    "https://www.mygeeks.com/"
]

Example 2:

// node program to demonstrate the
// url.toJSON() method in node.js

// Require an URL module
const url = require('url');

// Creating and initializing myURL variable
var myurl = [
    new URL('https://www.geeksforgeeks.org'),
    new URL('https://write.geeksforgeeks.org'),
    new URL('https://www.practice.geeksforgeeks.org'),
    new URL('https://www.demo.geeksforgeeks.org'),
    new URL('https://write.geeksforgeeks.org'),
];

// Display result
console.log(JSON.stringify(myurl));

Output:

[
    "https://www.geeksforgeeks.org/",
    "https://write.geeksforgeeks.org/",
    "https://www.practice.geeksforgeeks.org/",
    "https://www.demo.geeksforgeeks.org/",
    "https://write.geeksforgeeks.org/"
]

Note: The above program will compile and run by using the node index.js command.
