FAQ

Frequently Asked Questions

Do I need prior React experience?
No. The masterclass starts in the raw DOM with fetch and vanilla JavaScript so you understand what React actually abstracts. By the time you get to React, everything clicks.
Why start with vanilla DOM before React?
Because most React confusion comes from not understanding what is happening underneath. Once you have written raw event listeners and fetch calls, React hooks and state stop feeling magical.
What version of Next.js does this cover?
Next.js with the App Router, Server Components, Server Actions, streaming with Suspense, and optimistic UI. You finish knowing how to build a modern production Next.js app.
How does this fit with the Backend Engineer Bootcamp?
They pair cleanly. The backend bootcamp teaches the server; this masterclass teaches the client that talks to it. Together they are the Complete Full Stack Bootcamp.
