EnterpriseJS Code Walkthrough

Whether you're new to JavaScript or transitioning into a professional role, this demo shows you how to:

Understand destructuring like a pro

Work with services and APIs using Axios

Use optional chaining and nullish coalescing cleanly

Mock backend APIs using json-server

Test endpoints with Postman — no backend needed!

I also walk through a mini project structure that mirrors what developers see in real company codebases — no fluff, just real-world fundamentals.

Perfect for frontend devs, full-stack learners, and anyone tired of oversimplified tutorials.
