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One of the most frustrating aspects of learning a new technology is the overwhelming amount of out of date resources that exist.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dependencies, make sure your code matches the instructor's, but everything is broken because the instructors code is out of date.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 super love the course. Quickly got me up to date with Typescript. Although I've been coding Typescript for a while, I only felt I got the fundamentals down after this course. Highly recommend.

    Great course! The way information is presented is very clear and easy to follow. Video+text transcript is perfect. If this course would be updated with EC2022, I would take it again :)

    This was, pretty cool, I liked that there were not only theory but and a good examples of code. And quizzes is very cool, because you can test what you learned.

    One of the better courses I've seen for Javascript. Had trouble understanding promise before and this course explained it really well.
