Closure Compiler

Closure Compiler is a powerful tool from Google that transforms your JavaScript into more efficient, production-ready code. It analyzes your scripts to remove unused code and dead code paths, significantly reducing file size and improving load times. Beyond minification, it performs advanced optimizations like variable renaming and statement reordering. It also acts as a type checker, catching syntax errors and undefined variable references early in development. This results in cleaner, faster, and more reliable web applications.
