Have you ever wondered how JavaScript functions can "remember" things even after they've finished running? That’s the magic of closures, and today we’ll break it down with a simple use case:...
JavaScript中的闭包使得函数在执行后仍能记住外部变量。通过自定义计数器，我们可以理解闭包的概念。每次调用makeCounter()都会生成独立的计数器，闭包确保计数器在多次调用中保持状态，从而简化状态管理。
