Please accept the following terms and conditions before reading this article...!
- By "best" I mean "the most popular general-purpose projects". All are free/open source but the list may not include your favorites.
- Discontinued projects such as YUI are not included even though they may still have high use across the web.
- Only client-side projects are referenced. Some can work server-side but the list does not include pure server-based frameworks such as Express.js or Hapi.
- Information about each project is intentionally brief to provide an overview for further research.
