Remember last time, I said that there's different kinds of complexity in our code, and I suggested for simple branching programs, the amount of time it takes to run that program is, in essence, bounded by the number of instructions, because you only execute each instruction at most once.
但是这里有个很重要的点,记得上节课,我提过在我们的代码中,有不同种类的复杂度,而且我还说了对于简单的分支程序,运行这种程序需要的总体时间,大体上,是和指令的数目相关的,因为每个指令只会被执行最多一次。
So conceptually the key difference here, besides the syntax looking slightly different, it just means that if you want a chunk of code to execute no matter what initially, ; you can use the do while loop; if you want to check a condition first, you can use the while loop.
所以概念上,则关键的区别是,除了语法看起来有点不同,它的意思是如果你想要一段代码,最初无论如何都要执行,你就可以用do,while循环;,如果你想要先检查条件,你可以用while循环。
As an aside, if you ever just have one line of code that you want to execute, one puzzle piece in Scratch terminology, ; you actually don't need the curly braces; you only need the curly braces if you have two or more lines of code that you want to execute if that condition is true.
此外,如果你只有一行代码,需要执行,在Scratch,术语中叫做,一句代码,你就不需要使用花括号了;,如果那个条件成立,你有两行或更多行的代码时需要执行时,你就需要花括号。
