函数式编程是一种编程范式,主要是利用函数把运算过程封装起来,通过组合各种函数来计算结果。函数式编程意味着你可以在更短的时间内编写具有更少错误的代码。举个简单的例子,假设我们要把字符串functional programmingisgreat变成每个单词首字母大写,我们可以这样实现: ...

If you're using the compiled (or minified) bootstrap.js, there is no need to include this—it's already there. What's inside Transition.js is a basic helper for transitionEnd events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition ...
