26 Open Source JavaScript Libraries & Frameworks

As a longtime JavaScript developer there are still dozens of libraries I have never touched before. Many concepts are out in the wild that I can’t even wrap my head around! Prototypical JS templating is one, and full MVC control is another. But these libraries are seriously powerful and beneficial to those who understand them.

In this gallery I’ve organized a handful of very useful and free JavaScript development libraries. Each provides a different purpose where some are general libraries, others are complete frameworks to construct web applications. Even if you’re not a developer it’s still good to familiarize yourself with the vast collection of libraries out there. See if anything from this post catches your attention.
