All courses are up to date, guaranteed

One of the most frustrating aspects of learning a new technology is the overwhelming amount of out of date resources that exist. You've probably experienced it before - half-way through a blog post only to realize that what you're learning is an old API and the new one is completely different. Or worse, you purchase a course, install the dependencies, make sure your code matches the instructor's, but everything is broken because the instructors code is out of date.

When starting this site, my only goal was to create the resources I wish existed when I was starting out. Part of that includes having courses which are free from breaking changes so students never have to worry if a certain course is up to date.

Here are the details. Within 60 days of a breaking change, all courses will be updated to reflect the new API. If not, you'll receive a full refund for what you paid during those 60 days as well as any additional days that the breaking change(s) persist.

    As someone nearing the end of my bootcamp, my instructor recommended this course to cement my knowledge. This was great to revise topics different to how they were originally explained, especially how you covered Promises. On to the Advanced now!

    This course really helped give me a great understanding of React concepts, and was one of the best study materials I've used yet. I can't wait to learn from the other courses.

    I liked this course a lot, you really can explain some fundamental and complicated things very clearly. From all other courses and articles, I honestly think you are the best teacher. Hope I'll pass the curriculum successfully and will move on to another course. I really want to write some feedback about how to improve the course, but I just can't :)

    Clear and right to the point. After taking this course I can finally say I understand Hooks and I know how I should be using them. I really liked the platform and the content, also the practices helped me understand more.

    The course was amazing, Tyler does an amazing job of covering all the key React concepts(all up to date to) in depth. When you complete this course you really feel that you have a wonderful grasp on all the essential React fundamentals. Tyler does a great job of explaining hard to grasp concepts in a new way that really helps you to understand them, for example his explanation of higher order Components, render props and the context API, finally allowed me to fully understand these concepts that I previously had trouble with from other React courses. Thank you Tyler!

    The course is amazing, Tyler examples are good, I only missed homeworks and exercises more hands-on'ish than the questions after each section. But I was able to understand everything, really worth it.

    This is the best React Hooks course I have seen so far. The advanced hooks are a great addition to my toolkit. Thanks for the awesome course Tyler!
