致电与申请之间有什么区别? - What is the difference between call and apply?

问题:

What is the difference between using call and apply to invoke a function? 使用callapply来调用函数有什么区别?

var func = function() { alert('hello!'); }; 

func.apply(); vs func.call(); vs func.call();

Are there performance differences between the two aforementioned methods? 前述两种方法之间是否存在性能差异? When is it best to use call over apply and vice versa? 什么时候最好使用call apply ,反之亦然?
