But even with the simplicity of this loop construct, you can build any complex loop.

然而仅仅使用简单的循环结构，您也能构建任意复杂的循环。

In cases where the loop iterations are less than 1,000, you're likely to see only an insignificant amount of performance improvement over using a regular loop construct.

如果循环迭代次数少于1 ' 000次，你可能只看到它与普通循环相比只有微不足道的性能提升。

That is basically saying, given some collection of data, I want to have again a looping mechanism, where now my process is, walk through this, the collection one element at a time. And for that, we have a particular construct, called a FOR loop.

现在我的过程就是,通过一个个访问这个集合中,的元素的方式，来遍历这个集合,为了达到这个目的，我们有一个特定的结构，成为FOR循环。
