javascript - 什么是闭包编译器？

Question

如果您不知道我在说什么，请查看:http://closure-compiler.appspot.com/home (它是一个 JavaScript 压缩器)

---

在他们的网站上，他们声明如下:

The Closure Compiler compiles JavaScript into compact, high-performance code. The compiler removes dead code and rewrites and minimizes what's left so that it downloads and runs quickly. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. These checks and optimizations help you write apps that are less buggy and easier to maintain.

但是有人真的可以详细解释这个 Closure Compiler 对我的代码做了什么吗？

Answer 1

Closure 编译器将编译您的代码，并对您的代码执行标准优化技术。

从表面上看，生成的代码可能相似也可能不相似，但通常工作完全相同。
