JavaScript optimizing compiler

 Closure Compiler is a JavaScript optimizing compiler. It parses your
 JavaScript, analyzes it, removes dead code and rewrites and minimizes
 what's left. It also checks syntax, variable references, and types, and
 warns about common JavaScript pitfalls. It is used in many of Google's
 JavaScript apps, including Gmail, Google Web Search, Google Maps, and
 Google Docs.
