javascript - 网络数据如何显示在网络浏览器中？

Question

我之前从 Mozilla 的网站上读到这篇文章，我对客户端代码的工作原理有疑问。

You might also hear the terms server-side and client-side code, specially in the context of web development. Client-side code is code that is run on the user's computer — when a web page is viewed, the page's client-side code is downloaded, then run and displayed by the browser. In this JavaScript module we are explicitly talking about client-side JavaScript.

当代码被“下载”并被浏览器运行和显示时，代码下载到哪里了？它是临时下载或存储在用户计算机上的，还是永久的？
