Open Source JavaScript Libraries

QuoJS is a lightweight JavaScript library aimed at building mobile-first web interfaces with a focus on touch interactions and simple DOM utilities. It provides a compact, jQuery-like API for element selection, traversal, and manipulation, but trims the surface area to keep payloads small for mobile browsers. A core feature set centers on high-level touch gestures—such as tap, double-tap, swipe, pinch, and long-tap—abstracting away platform quirks so developers can attach handlers consistently across devices. The library embraces modern browser features and CSS3 where available, offering helpers that make common mobile UI patterns feel responsive and fluid. Because it is intentionally minimal, QuoJS plays well as a drop-in alongside other client libraries when you only need fast gestures and a few utilities rather than a full framework. Its API is designed to be readable and chainable.
