I loved the demystification of the library: creating a version of TSQ to see what's happening under the hood. I really liked the variety of real-life scenarios we got the explore! I learned a lot and I think I got a pretty solid grasp on TSQ's philosophy, so reading docs from now on should be a breeze! One thing that's missing is some discussion of TS (I think it warrants at least a chapter for some real life examples) and maybe some more complex cases for mutations, e.g. with `mutateAsync`.

The challenges actually helped solidify the concepts and they're practical and directly applicable to real work.

The "why" behind the "how" in React.gg has made a huge difference.

Pacing is great and there's a lesson that covers just about everything you'll think of during your learning process.

Repetition just helps you get better, though!

It's very easy to fall into it and I was expecting some info/tipps to avoid it.

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.

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 needed to learn Tanstack Query quickly for my job, and this course did not disappoint. I came away with not only a solid understanding of the library, but a new appreciation for the possibilities of what online courses could be. Thank you!

I had some prior experience with React Query before starting this course, but the initial sections provided excellent refreshers and introduced new insights I hadn't encountered before. As I progressed to the later sections, I gained a deeper understanding and the challenges were instrumental in solidifying my grasp of the material.

I love that this course explains concepts in React in a very thorough, in-depth way, and it does so incrementally. You learn a lot about how things work behind the scenes, and very importantly, WHY they work the way they do. I loved the interactivity in the lessons and challenges. Fantastic course!

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.

I was already familiar with most of the topics in this course, but I didn't know the exact details behind the scenes. The way the course is structured and how every tiny detail is explained is fabulous.

I've been working with React & Typescript for a couple of years now and I wanted to catch-up with some of its new features. This course surprised me with the tons of up-to-date information, hands-on exercises, and easy to understand explanations. I've learned a bunch of new stuff!

So many insights of redux, Awesome course!

TypeScript

Generally, my opinion is that the course is good, however there are quite a lof of concepts that are swept through, the examples are very fast paced and often times complex and hard to follow for someone that is just learning typescript for the first time. I think a longer, more slower paced course would be better to fully understand everything.

The course is well-designed and informative. However, if purchased individually, it might not feel like good value for money. Love the fact that the videos were small.
