JavaScript - 如何了解 "closures"的用法？

Question

来自维基百科，免费的百科全书:闭包(计算机科学)

In computer science, a closure is a function that is evaluated in an environment containing one or more bound variables. When called, the function can access these variables. The explicit use of closures is associated with functional programming and with languages such as ML and Lisp. Constructs such as objects in other languages can also be modeled with closures.

要在 JavaScript 中使用它，有人可以给我举一个例子来说明它是如何应用的吗？
