The 10 GitHub repos new developers mention the most (Part 1)

Ngoc Huynh

The freeCodeCamp community generates gigabytes of data each week. One of the most active parts of the community is the chat room system. Thousands of people hang out there, chat about technology, and help each other improve their code skills.

I frequently ask questions of the data. This week, I was curious which GitHub repositories people found to be the most relevant to their studies. So I analyzed the multi-gigabyte chat history from freeCodeCamp’s main chatroom.

Out of the thousands of GitHub repositories mentioned, here are the 10 most-commonly mentioned ones:

1. freeCodeCamp/freeCodeCamp

You probably saw this one coming. But this isn’t just because of where I got the data from. The freeCodeCamp community’s learning platform itself is quite popular, with nearly 250k stars, more than 10k forks, and hundreds of new issues and pull requests each week.

Thus, people mention it in the chatroom quite a bit.

2. getify/You-Dont-Know-JS

Kyle Simpson’s You Don’t Know JavaScript is without a doubt the unofficial reference book for the freeCodeCamp community. Kyle is also currently working on another similar project as YDKJS, “Functional Light JS”, which is gradually getting mentioned more and more.

3. vhf/free-programming-books

A frequently updated list of free resources. This repository is a well organized compilation of material collected from many parts of the world. It includes books, podcasts, websites, developer tools… you name it. Definitively a “must” for people who are learning to code.

4. twbs/bootstrap

The Github account of Bootstrap, the well-known responsive web design framework. The repository provides mostly technical information, but also has additional links to other useful sites. If you’re looking for more detailed documentation about the framework, you should also visit

5. jwasham/coding-interview-university

Googley as Heck created this repository to document his 8-month process of preparing for the Google interview. It includes a detailed list of the things you should know to pass Google’s infamous whiteboard tests, and links to references that clearly explain various computer science concepts. (By the way, after all this preparation he took a job at Amazon instead.)
