Questions

Is this a video course?

No. React Simplified is an interactive online book. Each topic is a short card you read, with code examples and an interview question. There are no videos to watch.

Who is it for?

Developers preparing for React interviews, and anyone who knows modern JavaScript and wants a structured, fast way to learn or revise React with TypeScript. It isn't a beginner JavaScript course.

Which React version does it cover?

React 19 with TypeScript, including Actions, the use hook, the React Compiler, Server Components and the latest Router, Redux Toolkit, Zustand and TanStack Query APIs.

Do I need to install anything?

No. The book runs in your browser. Your progress, review list and theme are saved in that browser on that device.

Can I try it before buying?

Yes. Chapter 1 is free: scroll it in the phone at the top of this page, or open it full screen.
