Velocity.js
Velocity is an animation engine with the same API as jQuery's animate. It works with and without jQuery. It's incredibly fast, and it features color animation, transforms, loops, easings, SVG support, and scrolling. It is the best of jQuery and CSS transitions combined. Download Velocity, include it on your page and replace all instances of jQuery's animate with velocity. You will immediately see a performance boost across all browsers and devices, especially on mobile. Velocity works everywhere, back to IE8 and Android 2.3. Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance.

Mobile Angular UI
Mobile Angular UI is a mobile UI framework just like Sencha Touch or jQuery Mobile. If you know Angular JS and Twitter Bootstrap you already know it! Mobile Angular UI provides essential mobile components that are missing in Bootstrap 3, switches, overlays, sidebars, scrollable areas, and absolute positioned top and bottom navbars that don't bounce on scroll. It relies on robust libraries like fastclick.js and overthrow.js to achieve a better mobile experience. No jQuery dependencies, no fat bootstrap js. Just a few angular.js directives are super easy to learn to put things together. Mobile Angular UI retains most of the Bootstrap 3 syntax. This way it’s trivial to bring an existing desktop web app to mobile. Also, a super-small CSS file is provided to do the opposite. Just include it and you’ll get a fully responsive and touch-enabled interface that can be used everywhere. FontAwesome Icons are included by default in place of Glyphicons.
