This is perhaps the most interactive JavaScript course ever recorded. It contains 140+ coding challenges, meaning that you will finally build that ever-so-important JavaScript muscle memory. You will solve the challenges directly in the browser thanks to Scrimba's interactive video technology, so there's not setup needed.

Say goodbye to "tutorial hell" and get ready to start feeling your JavaScript superpowers grow exponentially. Another unique thing with this course is that you will build projects from the very start. Instead of long and boring theoretical lessons, you will dive head-first into building products and solving challenges. At the end of the course, you will have built a game, a Chrome extension, and even a mobile app the uses Google Firebase to persist data. This is learning by doing on steroids.
