Summary

This page contains a collection of practical exercises to test your understanding of built-in modules, asynchronousness, and mini projects. Regular exercise makes the concept a habit and helps you recognize common patterns that emerge in the workplace. Work while still referring to official documentation when in doubt. (Node.js)

Key points

Practice the core concepts: event loop, callback, promise, and error handling.
Work on built-in modules: fs, path, http, events, stream, child_process.
Make small projects: file servers, CLI to-do, parser, or simple chat bots.
Always write a test for your utility function; the test speeds up feedback.
