freeCodeCamp is a free, self-paced curriculum for learning to code, published as open source at freeCodeCamp/freeCodeCamp. It's a 501(c)(3) nonprofit funded by donor support, structured around six certifications in its Full-Stack Developer Curriculum, each gated by required projects instead of open-book quizzes. The repository also carries beta language certifications for developers, interview-prep resources, and the code that runs the live freecodecamp.org platform.

Per the repository's own README, Vue 2 hit End of Life on December 31, 2023, is no longer actively maintained, and the project now directs users toward vuejs/core (Vue 3) and an official migration guide, while leaving Vue 2 itself installable through CDNs, package managers, and GitHub.
