Give you some examples. What have we talked about? We've talked about things like using comments to highlight what you're doing in the code, to make it easier to debug.

Can't use them on Booleans, they have a different set of things. They do things like AND, and OR. And of course there's a bunch of other ones in there, I'm not going to put them all up, but we're building up a little collection, if you like, of those operations.
这个方面的东西,它们不能被应用于布尔类型,布尔类型有其他的一系列操作,比如AND,和OR之类的,当然还有很多其他的,我不会把他们一一列出来,但是我们会学习这些操作的一部分。
Sometimes the functions -- sometimes a function can be used on multiple data types, plus, for example, we saw could add strings, or could add ints, but each one of those data types has associated with it a set of functions that are geared to handling them.
比如说,我们可以对string类型,进行add操作,也可以对int类型进行这个操作,但是这些数据类型中的每一种,都与适合于操作它们的,方法集相关联,我们想对我们创建的数据,类型做同样的事情。
