Form File or Directory Path String in Node.js

Path module in Node.js provides utilities to work with file or directory paths. It can be accessed using:

const path = require("path");

If we need to join different path segments to form a valid path string, we can use path.join().

const filePath = path.join("apple", "banana", "orange"); // apple/banana/orange

The separator used to join the path is platform specific. Based on the OS, path.join() automatically handles it.

All the arguments passed to join() should be a string. Otherwise, it will throw a TypeError.
