Closure Compiler 20140814

The best JavaScript compiler around, a tool to optimize JavaScript code, created and used by Google and many others around the Web
The Closure Compiler was written in Java and it has for many years achieved the best results when it come to analyzing, validating, and compressing JavaScript code for the Web.

It's unique from other compilers not only because it compresses code better, but it also checks for errors, unsused code, and even goes on to rewrite some of it for you when it detects bad syntax.

It's a powerful tool that has gained the respect of developers after they have seen what great JavaScript-heavy applications Google has built with it. Like per example the Google Search Engine, Google Maps, Gmail, and Google Docs, just to name a few.

The Closure Compiler can be used via a Java CLI tool, but it can also be hosted online and work via a simple interface.

A RESTful programmatic API is also available for developers that want to integrate it within other services as well.

What's New in version 20140407
  • Add a warning for the use of goog.base for projects that want to support strict mode in uncompiled code.
  • Add "arguments.callee", "arguments.caller", "Function.prototype.arguments" and "Function.prototype.caller" to the "strict" mode checks.
  • Have the runtime type checker type-check Object as any object type, possibly with an exotic prototype - not necessarily inheriting from a standard Object.
  • Move the checking for 'with' statements into the StrictModeCheck.
