an interpreted language is often easier to debug, because you can still see your raw code there, but it's not always as fast.
解释语言调试起来很容易,因为你可以看到最原始的代码,但是这种语言不够快。
Another way of saying it is, anything that uses get float doesn't care what the details are inside or shouldn't, and if I change that definition, I don't have to change anything elsewhere in my code, whereas if I just have the raw code in there, I have to go off and do it.
换种说法就是,任何用到获取,输入这个功能的人不用担心具体的实现细节,如果我改变了这里的实现,我并不需要去改变我的代码,因为我的最底处的源码就在这里,我去改这里就可以了。
