In addition, a screen or control can define local state (using variables) and use control structures to iterate over collections and conditionally show parts of the user interface.

此外，屏幕或者控件也能够定义本地状态(使用变量)，并使用控件结构来对集合进行迭代，从而根据条件显示用户界面的各个部分。

Well, because the memory we've been using for local variables, and for functions, storage space is what computer scientists generally call the stack.

好的，因为我们看到的内存是用于局部变量的，用于函数的，存储空间就是计算机科学家,通常说的堆。
