Learning React Sucks

You’ve probably gone through dozens of tutorials, tried reading the docs, and maybe even paid a few bucks for a Udemy course – but as soon as you try building anything on your own, 💔.

It’s not your fault.

The state of learning React today has never been more of a mess. It feels like 50% of the resources are out of date, 30% are inaccurate, and the rest is AI slop.

The problem, as I’m sure you’re also aware, is React is the most important piece of technology you can learn if you’re building any sort of UI, and with AI’s increasing reliance on its component model, it’s only growing in demand.

This is why we spent (literally) years building react.gg.

It’s the culmination of everything we’ve learned since we first started teaching React way back in 2015.

In that time we’ve helped thousands of developers of all skill levels master React, and I think we can do the same for you too.

What you’ll learn

Optimized for aha!

We’re obsessed with helping you reach your aha! moments.

Our text sections help you master the why behind React concepts and include fun, interactive visuals you can play with.

Give it a try.

Leetcode for React

Have you ever wished you could “grind Leetcode” for a bunch of React practice problems?

No? Oh, well we built it anyway. You’ll know you’ve mastered React if you can get through all 90.

These aren’t lazy screencasts filmed in someone’s guest bedroom.

We spent an uncomfortable amount of time making sure each video is worth your attention.

50 custom hooks

To make the course as "real-world" as possible, we built useHooks — a library of 50 custom React hooks that now gets over 300k downloads a week.

You’ll solidify what you learn by rebuilding it. Yes, all 50.

    What is the difference between React.startTransition and the startTransition you get from useTransition?

  • Quiz yourself

    What's the main benefit of using actions over managing loading state manually?

Future proof React

React has evolved a lot in the last few years, and it shows no signs of slowing down.

“react.gg is incredible. The way in which the team has been able to deconstruct even the most complex aspects of React into a fun, easily consumable package is inspiring. By far the best way to learn React.”

Reviews

Still not sure? Here’s what people have been saying about the course.

  • Luax ⚡️

    I recently completed the React course on react.gg and found it to be fantastic! The platform is well-designed and easy to use, taking a logical approach to teaching React from beginner to advanced concepts. The playground is also great for practicing and experimenting with code. Highly recommended for anyone looking to learn React!

    I love everything about this course, honestly. The teaching, storytelling, the whole styling and presentation, the density and intensity, the interactivity and those small traces of humor here and there. You’ve done a fantastic job. It’s worth every cent.

Frequently Asked Questions

Is there a way to preview the course content before purchasing?

Yes. You can get a feel for what the course will be like as well as take a few of the lessons, quizzes, and challenges from the course dashboard.

Also, you can play around with React, Visualized, a collection of interactive visuals taken from the course. Or dive into useHooks, a library of modern, server-safe React hooks which you’ll rebuild throughout the course.

Are there any pre-requisites for this course?

Yes. You need a solid understanding of HTML, CSS, and JavaScript. If you don’t know what a callback is, react.gg might not be a great fit for your current skillset. However, you’re welcome to try.

Am I too senior for this course?

Probably not. If you can confidently rebuild all 50 hooks from the useHooks library with the latest React APIs like useSyncExternalStore, useEffectEvent, useTransition, actions, and transitions – then yes, you’re probably too senior.

Does this course have captions?

Yes.

Do you get a completion certificate?

Yes.

Does the course use TypeScript?

It doesn’t. We want the course to be as accessible as possible, so we chose to keep the number of pre-requisite technologies to a minimum. Regardless of whether you know TypeScript or not, you’ll still get a lot out of the course.

Can I get an invoice?

Yes. After purchase, you’ll have the ability to fully customize and download your invoice with all the information you and your employer need.

What do I do if I get stuck?

Each lesson has a public discussion thread embedded in the lesson where you can ask questions and get help. Course instructors are also notified and can help you out.

How can I get this for my team?

You can change the number of course licenses you’d like to purchase on the checkout page. After completing your purchase, you can easily distribute your licenses to your team members.

Does the “Expansion Pack” include lifetime access to react.gg?

It doesn’t. Think of the “Expansion Pack” as a subscription to Fireship Pro. You’ll get access to all of the content for as long as your subscription is active (like Netflix).
