Leverages cutting edge browser APIs including WebRTC, FileSystem, Video, Canvas, Web Workers, Typed Arrays, and Base 64 Encoding to support over 20 options. By harnessing the power of web workers, you get fast GIF creation that doesn’t block the UI. An image quantization algorithm is also used to reduce the number of colors required to represent the image.

8. Gander

Gander, in its most basic form, wraps itself around functions to provide execution times. Times are provided in sub-milliseconds when the precision is available (process.hrtime, performance.now) and milliseconds when not. Gander supports CommonJS/node.js and AMD/require.js imports. You can also use it in your web app via a normal script tag and it will add itself to the window object.

9. Midnight.js

Midnight.js lets you switch headers on the fly. All you have to do is create your nav (or header) as you normally would (as long as it works with position:fixed), and then Midnight.js helps you change that header when necessary for different sections.
