It's a fantastic resource if you’re looking to deepen your understanding of React or you're just starting. Everything regarding the contents of this course is GOLD. The combination of practical challenges, clear explanations, and engaging lessons truly makes the knowledge you gain stick! That can't be said for the built in text editor. It lacks basic functionality. There is no diagnostics, no lsp functionality at all and no Vim keybinds. In a world where exists Monaco is plainly unacceptable.

Each lesson breaks down the concepts in digestible pieces and are delivered with common sense. Some topics I have previously had trouble understanding, such as Promises & async/await all make sense now because they built up from their core components, and the why as well as the how, and the how-we-got-here are communicated clearly.

We’re refactoring a large app to use React Query. The docs have been really useful but this course takes it to the next level.

I just completed the course that was outstanding from start to finish. The highlight for me was the initial section, where we recreated React Query from scratch. This deep dive into the core concepts provided a solid understanding of how React Query operates under the hood, which added immense value for someone who’s been using it for the past three years. The explanations were perfectly clear, making even complex ideas easy to follow. As a result, I've already started applying new techniques at work, especially in how I manage query options, and handle pending and error states. This course genuinely elevated how I approach async state management. I’d highly recommend it to anyone interested in improving their app's async state management. Whether you're new to React Query or an experienced user, this course is packed with insights that can reshape your approach.

The "lectures" were very detailed and explained topics in a way that were easy to understand. I really enjoyed that. However, the external VSCode practice problems were a struggle. There were constant errors popping up that would often break the output view and there were a couple that seemed to have minimal instruction, so I didn't really know exactly what was being asked of me. I completed the react.gg course and the integrated development environment was a massive improvement over using external tools. This Typescript course needs to implement that to be sufficient.

I really enjoyed the material covered in this course. I wish there were mini-games, exercises, or small projects to help reinforce the learning. I re-watched each episode twice, once for an initial overview and the second for detailed note-taking, and then practiced (breaking/rebuilding/implementing) the code examples used throughout the lessons. This method allowed me to generate questions and seek answers through external videos and resources while providing a way to reinforce what I learned. The lessons in this course provided a detailed overview of JavaScript; while some lessons left me confused or asking questions, it did, however, provide a great path to ask the questions that I didn't know needed to be asked to fully understand the concepts in each lesson.

This course will skill up any person aside from the React Core team. I appreciate that I don't have to spend wasted learning minutes setting up a repo. I can just open a browser and pick up where I left off. I recommend this to everyone, no matter your seniority level in React.

The nexus between the topics, quizzes, project implementation and practices is impressive. I also appreciate the way approaches's pros and cons were introduced, discussed and solved. Great work and thank you for putting this course together.

I'm mostly a backend/AI software engineer (used to work at Google, lots of C++ and python) but not a frontend person, using this course to learn about React/JS. I'm most of the way through the course now, and it was great. I'm fairly new to React, and had read several books etc, but this clarified things much more than my reading did. Also, although it starts out easy, the course ramps up in difficulty, so I think there is something for everyone here.Since I'm new to JS in general, so learning about some of the browser APIs was also useful for me. The main (positive) surprise I had was that often the videos went too fast for me in places and I had to rewind and rewatch sections, pausing to give me time to think (normally I find videos too slow and always watch at 2x, but on this one I only did 1.5x or 2x in a few places and 1x more often since it was already running at a good pace). I liked it that it wasn't full of slow, boring, fluff content. I had to stay engaged the whole time.The videos are also delivered in written-out text form, with slightly different content, and that was really useful to give me more time to process. Great idea to include both. The course is highly interactive, and this is a great help for learning. I found myself pretty humbled by most of the coding challenges, since I usually was failing at least one test, and often had to look at the hints to get unstuck. That's a great sign that I had a lot to learn and that it's sufficiently challenging.

Amazing course, it combines theoretical and practise parts.

Redux

14 months ago

It was a great introduction to Redux! I really like the approach you've taken of building your own mini-Redux from the ground up, to then swap in the real package. I had moments where I was initially disappointed to see things being done in an "outdated" way, e.g. using class-based components, but then you later show how this can now be swapped out with functional components using hooks. I think that's a good way to arrive at the final solution, giving a solid understanding of why we would want to write it this way - however, I think it might be good to make it clear up front that you're essentially taking the "long tour", and that people following the course should "stay seated" until we reach the end. One thing that is really unfortunate though, is that it doesn't cover how to write "modern" Redux using Redux Toolkit, but instead teaches the "old" way of writing Redux, which requires a lot of boilerplate. I'd love to see this course get an update, or at least leave a note at the end that people should check out the Redux Toolkit.

Love the teaching method (learn -> quiz -> task -> solution), would be great if the course was adjusted to v6.4

People who already have their basics ironed out will benefit from taking this course. I do possess basic knowledge of JS, to some extent. But this course was a bit too far ahead for me. I'll need to work on my basics more. Overall it's a great piece of knowledge and I do not regret spending money on it. I might re-watch this course later. I hope ui.dev will create another course, "intro to js" soon. :)

I'm learning JS from scratch. Modern Javascript and the other courses in this site are both fun and informative. The team has done a great job in explaining the concepts in an easy to consume format.

I just unlearned and relearned some material. Overall, the course is terrific. I've been using redux for 2 years. With this course, I just strengthen my background in redux. Highly recommend for any beginner to react.

Despite having experience with JavaScript in previous years, I felt a void in my comprehension. However, this course bridged that gap and gave me a clearer mental framework. Thanks 🙏 I'd appreciate more quiz sections, especially ones with challenging questions tailored to each topic, to further assess our grasp on the material.

This course doesn't just teach you React it teaches you ABOUT React. And it does so in a way that is fun, challenging, and engaging.

I’ve been 'learning' React for four years now and got my first paying React job last year. But since starting React.gg, I’ve been surprised by how my React intuition has skyrocketed! I am learning soooo much, and best of all I’m having fun doing it!

I think any front end developer or even full stack who want to improve their JS skills, especially the basics which sometimes can be over looked, can really benefit from this Modern JavaScript course! :)

I was always struggling with TypeScript, but after completing this course I'm feeling relieved because now I can understand it way better, but also I'm feeling excited to put all the gained knowledge into practice.

The way that challenges are continuously used in this course with the newly implemented ui.dev challenge software is outstanding! Being able to watch a video, read the same content, do a quiz question, and then practice with challenges that give you instant feedback is unmatched. Thank you, ui.dev!

Tyler's teaching method is great. He manages to cover a lot of detail and answer the important questions while demonstrating with code, without turning it into a long winded lecture. This is something a lot of teachers struggle with getting right but Tyler seems to be a natural at it. I've been doing JS, TS, React, and Vue for a while now and still learned a lot from this beginner course.

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.

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!

If you have zero experience or you have some experience this course will teach you something, or it will clear some things for you that was unclear before. Also if you only learned React without diving into javascript at first you will understand much more of how it works in the back

The course is really fun and is created using articles and videos, so you learn the same concept twice in different mediums. This is perfect because it helps you understand hard concepts such as when and why React renders. After months of trying other resources, I finally feel like I am learning React for good. Thank you ui.dev team!
