15 GitHub Repos That Every Developer Must Bookmark Right Now

Over the last few years, GitHub has become more than a mere versioning-control system. It is a one-stop place where developers collaborate and contribute together that forms such a strong community and an enormous network among the developers and programmers. But finding useful repositories has been an uphill task for many.

As per Wikipedia, GitHub reports having over 40 million users and more than 190 million repositories making it the largest host of source code in the world. The sheer mass also comes to the problem to find the most useful repositories available out there. Hence, I have put together a list of GitHub repositories that would help you to learn and grow as a software developer.

The majority of the ebooks are on programming, and it has been expanding ever since.

John Washam, now a Software Developer at Amazon, had created this initially as a short to-do list of study topics for becoming a software engineer, but now this repo has grown bigger and better with time.

Programming has been one of the most satisfying jobs for people who share their knowledge and contribute to the developer community. I am sure you would love to do that too (if you haven’t already 😉).
