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One of the most frustrating aspects of learning a new technology is the overwhelming amount of out of date resources that exist.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dependencies, make sure your code matches the instructor's, but everything is broken because the instructors code is out of date.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.

    I used Redux in many projects, but I never felt comfortable using Redux until taking this course. Thank you Tyler!

    Prior to this course, my experience in JavaScript was from a bootcamp instructor who didn't use english as his/her first language. Going through this course gave me more clarity on JavaScript concepts that remained foggy from my bootcamp. Excellent course and gave me a way better understanding of JavaScript!

    This course is just excellent. As always, Tyler delivers on his First Principles approach to learning, taking time to explain not only the "hows" but more importantly the "whys" regarding, in this case, the Hooks way of doing things. I 100% reccomend this course to anyone who wants to learn React Hooks.

    Easily a five! While I was familiar with the topics I found I learned something new in each section. Specifically the ES modules, I didn't know it was now possible to implement that without Babel. I thoroughly enjoyed the course, thank you for making it!

    As I developer who has been using TypeScript for 2 years a learnt a lot! It's not too fetched while managing to cover every topic. It's also great that I have an option to choose between text and video materials.

    I took this course to see what I was missing in React and it turned out I learned more things about JavaScript...lol. Other than that it had a great pace and I would recommend it to anyone (err everyone)!
