Another important aspect of global variables is that where security of the information is an issue, controlling access is possible.
全局变量的另一重要方面是，在考虑到信息安全性时，可以对访问进行控制。
Closures are powerful because they enable inner functions to retain access to an outer function's variables even after the outer function has returned.

清单10向您展示了在需要时如何访问全局变量。
Although you should avoid name hiding (giving local variables the same names as attributes), the use of accessors to always access attributes means you can give local variables any name you want.
虽然应该避免名称隐藏(为本地变量赋予与属性相同的名称)，但是始终使用读写方法来访问属性意味着：可以为本地变量赋予任何名称。
We also refactor the code to have all three actions as fields (rather than local variables) so we can access them from three methods. Let's see the final version of Explorer (Listing 10).
我们还重构了代码，将这三个操作作为字段（而不是局部变量），这样我们就可以用三种方法来访问它们。
