About JavaScript30
It trains you to work with the DOM, events and built-in browser features. It suits beginner to intermediate developers who already know some JavaScript and want hands-on practice.
The course is free. You sign up with your email to get the videos, and all 30 days are open at once, so you can go at your own pace. Wes Bos made it.
