Testimonial

I was really struggling to feel confident in React, even though I had been using it for a while. Everything just felt messy and complicated. But after going through this course, my whole approach changed. Now, when I look at a complex React project, I actually know what’s going on instead of just guessing. HUGE confidence boost. Thank you for making this!!

Jared

Testimonial

Man, I just gotta say this course is insane. I thought I knew React, but I did not. Not like this. Every module kept surprising me with things I didn’t even know I was missing. Like, the way you teach data prefetching with React query? Why has no one ever explained it like that before? Seriously, thank you. This changed my life.

Robert

Testimonial

Wow, I understand everything so clearly now. The way you teach really resonates with me. Thank you for this, this is the most valuable resource I’ve ever seen for React. I didn’t know about all the router stuff and cache updates, but it makes so much sense when you teach it. I feel so confident in my abilities now and have already started applying what I’ve learnt to my own code. Thank you once again.

Testimonial

Just finished the course, and here’s my review. Honestly, this is the best React course out there. It’s structured so well, and every lesson builds on the last one in a way that makes it all click together. It is advanced, so make sure to have experience with React before getting it. But at the same time, it’s explained really well. The concepts are broken down in an easy to understand manner. I wish this existed earlier, it would’ve saved me so much time. If you’re serious about becoming great at React, take this course.

Turns out I only thought I knew React. 😅 The way everything is structured, the real-world project, the clear explanations… it all just makes sense. Like, I actually understand how to build a big app now. Before, I was just scared of it. On top of that, there’s the deep dives on tRPC, Tanstack router, prefetching and caching. There’s so much to learn. This is the best React course out there, hands down.

Omar

Frequently Asked Questions

Darius

Hey, I’m Darius! 🤙

You might know me from my YouTube channel, Cosden Solutions.

I've been working with React for over 9 years, building complex projects as both a team member within startups and corporations, as well as on my own as a freelancer. I've also dedicated long after-work hours to passion projects. I've learned a lot about React along the way, how it truly works under-the-hood, how to effectively use it, and how to build really big and complex applications with it.

In early 2023, I decided to start teaching React to others. I created a YouTube channel which has now grown to millions of views and tens of thousands of subscribers. As much of a success as the YouTube channel has become, I felt like I could do more. I wanted to create a course that would help people learn React in a way that I wish I had learned it.

I've designed my courses for those who are in the same position I was 9 years ago – feeling overwhelmed with React. There are so many tutorials and roadmaps out there, but the truth is, however much time you spend on them, when you eventually get that job you wanted or start building that project, if you're anything like me, you'll feel like an imposter.

All those tutorials and roadmaps showed you were small projects. And the thing on your screen now is BIG. This is how I made this course and kind of reverse-engineered them – starting from real concepts and real-world projects, you will learn everything you need to know about React and beyond, all while gaining confidence to handle a project of this size when the time comes.

My courses will prepare you for the real-world of React much more than any tutorial could and you will learn everything you need to become a great React developer.
