base2 - A standards-based JavaScript Library.与 prototype 相比更简洁，号称更 “javascript” 的javascript lib。

Because this library is standards-based it means that you don’t have to learn a new API. It uses standard DOM properties and methods throughout which also means that there is no need for a lot of accompanying documentation.

Highlights

* A fast implementation of the Selectors API

* Fixes broken browser implementations of the DOM events module including document.createEvent(), dispatchEvent(), addEventListener(), etc

* Supports DOMContentLoaded

* Fixes getAttribute()/setAttribute() (Internet Explorer)

* Implements getElementsByClassName()

* Implements a few other useful DOM methods like getComputedStyle() and compareDocumentPosition()

* Supports a variety of browsers including ancient browsers like IE5.0 (Windows and Mac)

* It uses standard DOM properties and methods

* It lets JavaScript look like JavaScript

* It doesn’t use the weird (but popular) “$”

* It doesn’t contain any visual effects

我个人其实不喜欢这些 js lib，它们让你开发更快，但也会使你丧失知情权。
