BetterScroll
Inspired by iscroll, supports more features and has better performance
...BetterScroll is implemented with plain JavaScript, which means it's dependency free. BetterScroll provides a class whose first parameter is a plain DOM object when instantiated. Certainly, BetterScroll inside would try to use querySelector to get the DOM object. In BetterScroll 2.X, we split the 1.X-coupled feature into the plugin to achieve on-demand loading and reduce the volume of the package.
