Now, efficiency is obviously an important consideration when you're designing code, although I have to admit, at least for me, I usually want to at least start initially with code that works, and then worry about how I might go back and come up with more efficient implementation.

现在，当你设计程序的时候效率,是不得不考虑的问题，虽然我必须承认，至少对我来说,我是先担心程序能不能运行,再去把它的效率优化的,我喜欢可靠点的东西。

What is this? This is a wonderful piece of abstraction. It is saying, you don't need to know squat about what's inside the body of this function. You don't have to worry about the parameter names, because they're going to be preserved, you don't need to worry about how I'm doing it, this tells you how you can use this, in order to use it correctly. Of course, I can then close it off, and off we go.

但是这能告诉你一些信息,这是什么？,这是一段完美的抽象,它的意思是你不需要知道,这个函数的内部构造，你不必担心参数是否重名，因为它们已经被预存了,你不需要担心我如何使用它,它告诉了你你该如何操作，从而正确的使用它，当然我也可以把它关掉。
