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
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.
