What people are saying

Before taking this course, JavaScript always felt impossible to understand. I'd tried dozens of tutorials but always gave up and felt demoralized afterwards. Less than a month since starting LearnJavascript Online, I feel empowered to develop my own projects.
The course is perfectly structured from start to finish, and enables you to learn by actively writing code instead of just reading / watching somebody else. Without a doubt, this is the best investment I've made in my own education as a developer.

I'm super impressed with how high the quality of this course is. I've used a few similar products in the past and this is easily the nicest to use. @luke_bennett_

I can't tell you how much fun this is. The step-by-step, cumulative, real-world application has helped me to cement concepts that I've struggled with for a long time. @windowswebdev
