What it is

This repository holds the source code and lesson content behind freeCodeCamp.org, a nonprofit learning site with thousands of interactive coding challenges. Learners work through certifications in responsive web design, JavaScript, Python, relational databases, and back-end APIs, building required projects and passing an exam to earn a verifiable certificate. It also includes language courses such as English for developers and interview prep material. Adults moving into tech careers study here, and volunteers contribute fixes and curriculum through the repo.
