The <a href="compiler/">Closure Compiler</a> 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 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. You can use the compiler with Closure Inspector, a Firebug
extension that makes debugging the obfuscated code almost as easy as
debugging the human-readable source.
