The Course is very good to brush up on your knowledge. The Only problem some may face is understanding the instructor's accent. Good course to go through before the interview.

By Juan Mora on 8/9/2025

Great course, it works perfectly as a refresher or a quick intro to a lot of features, it gives you a overall view and then you can go and dig in anything that you might be interested.

By Brian Dausman on 6/29/2025

It's a good crash course. Nothing is gone into too much of depth. A lot is glossed over or not explained WHY behind it. Repetitive for how short it is. But definitely helpful as a quick refresher.

By Mark Wangler on 6/11/2025

I like this because it's only a few hours. Other courses with the same material are 50+ hours, they are too big of a time commitment. This gentleman quickly explains the basics in a very good way.

By Anoop Vijayan on 3/10/2025

This is one of the best course to prepare for the react interview. Quick and Easy to learn with examples. One suggestion I would give is provide an explanation of the feature before start the demo, for example useState , "The useState Hook is a built-in React Hook that allows functional components to manage state". Simple like this helps us to answer better.

By Robert Chapman on 8/21/2024

Disappointing that two thirds of the code cannot be downloaded at all. No excuse for that when everyone else provides all the code samples. It's fairly basic a lot of the time with questions being "do you know about x?". But the explanations are quite clear and most people will learn (a little) something about each of those subjects. The custom hooks creation section though is excellent and worth the money on its own.

By Justin Turikumwe on 3/27/2024

The content is concise and well explained for pros.

By Sarah Fisher on 2/2/2024

The course is super helpful as soon as it hits react hooks. Before that it was too focussed on absolute beginners, but the hooks and custom hooks have been so useful for my interview prep.

By Animesh Kumar on 12/4/2023
