Q: What is the role of the path module and why is it preferred over manual string concatenation?

**TL;DR.** The node:path module builds and manipulates file paths **correctly across operating systems**, which use different separators ( / on POSIX, \ on Windows). path.join / path.resolve pick the right separator, normalize redundant slashes and .. segments, and avoid the subtle bugs of hand-built strings. manual concat dir + '/' + file wrong slash on Windows double // / no normalize <rect class='d-box-accent' x='240' y='30' width='200' he

Portable paths

import path from 'node:path';

path.join('users', 'arvind', 'file.txt');
// POSIX: users/arvind/file.txt   Windows: users\arvind\file.txt

path.resolve('config', 'app.json'); // -> /cwd/config/app.json (absolute)
path.extname('photo.png');          // -> .png
