What that basically says is the following: in an interpreted language, you take what's called the source code, the thing you write, it may go through a simple checker but it basically goes to the interpreter, that thing inside the machine that's going to control the flow of going through each one of the instructions, and give you an output.

也就说，如果是解释语言的话：,你要写一些叫做，源码的东西，你写的东西会经过一个简单的过滤器,然后解释器会处理你的源码，解释器会产生一个,逐条读取你的源码的,控制流，然后返回一个输出结果。
