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One of the most frustrating aspects of learning a new technology is the overwhelming amount of out of date resources that exist.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dependencies, make sure your code matches the instructor's, but everything is broken because the instructors code is out of date.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 loved how this course was very much targeted at intermediate/professional javascript users. I feel like this course has helped me develop an intuition around how to think about typescript. The course cadence is smooth and each section feels is appropriately ordered.

    Really fantastic course. If you're interested in TypeScript at all I can not think of a better value for your time. Each lesson builds upon the last so you are never left confused when the more advanced topics are covered. It's obvious a lot of work went into making this and the quality reflects that.

    I think this is one the best resources for learning advanced javascript. Tyler makes it so easy that you actually don't think that you've learnt it until you start exploring stuff (or in my case, go back to work). And I can't even begin to thank you for supporting the parity pricing. That was one of the reasons I was actually able to try this course

    Tyler, I really enjoyed this course. Though I was familiar with most of the subjects, it was great to learn about it in-depth, step by step, and see how and why things developed as they did. Making sense of these subjects makes it so much easier to remember them.

    Fantastic course. You can tell Alex put a lot of time and thought into how to structure everything so you feel the learning comes natural.

    Having started off learning ES6, this helped me easily understand what is happening under the hood.

    This course not only teaches you new concepts in ES6 but helps you understand how they work and what's under the hood.
