javascript - 我们正在从 .cache.html 文件加载 javascript，那么为什么我们不能从 .js 下载它呢？

Question

我在学习gwt时在developers.google.com上看到了以下句子。

"The "`cache`" files contain your application's logic. If you were to look inside a 
`.nocache.html` file, you would see that it is JavaScript code wrapped in a thin HTML
 wrapper.You might wonder why the `GWT` Compiler doesn't simply emit it as a JavaScript .js 
file. The reason for this is that certain browsers do not correctly handle compression of 
pure-JavaScript files in some circumstances. This would effectively mean that users 
unfortunate enough to be using such a browser would download the `.js` file uncompressed. "

我们正在从 .cache.html 文件加载 javascript，那为什么我们不能从.js下载它呢？我认为现在所有浏览器都支持 javascript..

Answer 1

引用的声明似乎已经非常清楚地解释了这一点:“某些浏览器在某些情况下无法正确处理纯 JavaScript 文件的压缩”。它不是支持 JavaScript，而是支持 JavaScript 文件的压缩。
