Frequently asked questions
How many open source projects are written in JavaScript?
This registry tracks 341 JavaScript projects, with 3,752,277 GitHub stars between them and a median of 2,996 stars. The most-adopted is ECC at 295,522 stars.
Which JavaScript projects are most actively maintained?
270 of the 341 projects were pushed in the last 90 days. Each entry above shows its exact last-push date, so you can filter out dormant projects before committing to one.
What licence are JavaScript projects usually under?
329 of the 341 carry an explicit open-source licence across 13 distinct licences, and the licence is shown on every card. Permissive licences (MIT, Apache-2.0) are the safest default for commercial use; check the copyleft ones individually.
Should I use JavaScript or TypeScript for my project?
Both are viable. JavaScript is the better default if your team already knows it or the libraries you need are written in it; TypeScript may suit you better if you need the ecosystem, tooling or performance profile it is known for. The registry lists 341 JavaScript projects to work from.
