所谓函数重载(method overloading)即函数名称一样,但输入输出不一样。也就是说允许函数有各种不同的输入,根据不同的输入,返回的结果不同。jQuery之父John Resig提出了一个非常巧(bian)妙(tai)的方法,利用了闭包。 假设有如下一个需求,有一个people对象,里面存着一些人名,如下: ...
to combine multiple stateful transitions over a function,Arrayallows us to create a newArraythat contains the results of calling every permutation of each element in two arrays over a function. We will use this ability to pull from two separate locations in ourAppStateand generate anArrayofCards...
