Coding Challenges
All our coding challenges are curated by the community, bringing in expert knowledge from volunteers like you.
You can help expand them and make their wording better. You can also update the user stories to explain the concept better or remove redundant ones and improve the challenge tests to make them more accurately test people's code.
If you're interested in improving these coding challenges, here's how to work on coding challenges.
Learning Platform
Our learning platform runs on a modern JavaScript stack. It has various components, tools, and libraries, including but not limited to, Node.js, MongoDB, LoopBack, OAuth 2.0, React, Gatsby, Webpack, and more.
Broadly,
- We have a Node.js based API server.
- A set of React-based client applications.
- A script that we use to evaluate our front-end projects.
Contributing to this requires some understanding of APIs, ES6 Syntax, and a lot of curiosity.
Essentially, we expect basic familiarity with some of the aforementioned technologies, tools, and libraries. With that being said, you are not required to be an expert on them to contribute.
If you want to help us improve our codebase, you can either use Gitpod, a free online dev environment
(Starts a ready-to-code dev environment for freeCodeCamp in your browser.)
OR
you can set up freeCodeCamp locally on your machine.
