Google Closure Compiler is a JavaScript-to-JavaScript compiler that parses, analyzes, and optimizes code by removing dead code, rewriting, and minimizing it. It also performs syntax, variable reference, and type checking, warning about common JavaScript pitfalls.

Use cases

• minify and optimize javascript bundles
• type check javascript with jsdoc annotations
• remove dead code from large javascript codebases
• make javascript download and run faster
• statically analyze javascript for common pitfalls
• compile javascript in advanced optimization mode

When to choose

• your codebase is written specifically for closure-compiler's advanced mode
• you need the most aggressive whole-program minification and dead code elimination
• you want JSDoc-based type checking of JavaScript
• you maintain a legacy Closure Tools-based project

When to avoid

• you have arbitrary third-party JavaScript not written for closure-compiler
• you want a modern bundler integrated with the broader JS ecosystem
• you rely on dynamic property access or hidden globals that the optimizer cannot see
• you only need simple minification - other tools are comparable and easier to use
