javascript什么时候初始化vars? [英] when does javascript initialize vars?

问题描述

var x = ["aaa", "bbb", "ccc", ...];
function f() {
  var y = ["aaa", "bbb", "ccc", ...];
}

至少在我看来，这是一个很大的问题.

It is a big array, at least in my opinion.

我假设 y 在每个实例中都重新初始化.

I assume y gets initialized again at every instance.

加载页面时，全局 x 仅会被初始化一次吗?似乎合理...

Would a global x be initialized only one time when page is loaded? Seems reasonable...
