每次变量变化时如何在JavaScript中运行函数？
问题描述：
JavaScript中是否有类似于侦听变量中的变化的事件？所以当它的值被修改时，事件触发，然后我可以调用一个函数。为了更好地理解上下文，我有一个处理对象数组的html呈现的函数，并且我希望每次修改数组时都会自动调用该函数。
Is there a way in JavaScript to have something like an event that listens to changes in a variable? so when its value is modified the event triggers and then I can call a function. To put this more into context I have a function which handles the html rendering of an array of objects, and I want that function to be called automatically every time the array is modified.
感谢。
