Reviews
Genuinely the best React course I've taken. Andrei explains the why behind every decision, not just the how. The curriculum feels current and the projects are real-world enough to put on a CV.
I've taken a few React courses before but always felt like I was patching gaps. This one fills in the foundations properly. The Redux Toolkit and Next.js sections alone are worth the price.
Very thorough. Lost a star only because some of the earlier sections felt a bit slow if you already know JS well — but skipping ahead is easy. The testing and deployment chapters were exactly what I needed.
Built my portfolio site from scratch following the Next.js section. Got two interviews out of it. Clear, well-paced, and the instructor genuinely responds to questions in the community.
