19 Valuable GitHub Repositories for Beginner Developers 📚✨

I have often been asked what resources would I recommend for beginners looking to step their foot into the web development career. I often refer to GitHub as a great place to start.

I decided to compile some of the best repositories I know. I wish I knew them when I started myself, so treat them as a valuable shortcut to speed up your learning path.

This article is obviously oriented on beginners, though I'm sure some of the more experienced developers might learn a thing or two from these, too.

To help you to navigate I have arranged them via categories, starting from basics to courses, handbooks, best practices, projects, interviews, and resources.
