Code Minifier

• Network Latency: Minifying files can reduce their size by 30-70%. Smaller files transfer over the network faster, drastically improving Time to Interactive (TTI) for users on slower 3G/4G connections.
• Gzip/Brotli: Minification works incredibly well alongside compression algorithms. Removing entropy (like unique variable names) allows gzip to achieve much higher compression ratios.

Minification is NOT Security!

While minified code is harder to read, it can easily be reversed using formatting tools (like the JSON Formatter or JS Beautifier). You must never hardcode secrets, API keys, or proprietary business logic in client-side code, as anyone can inspect it using browser developer tools.

• Regex Fallbacks: Since this tool runs directly in the browser and must be fast, it uses highly optimized Regular Expressions to target block comments /* ... */ and line comments // ....
• Web Workers: If the text payload is extremely large, the stripping process is offloaded to a background thread to prevent UI freezing.

• Terser: The modern standard for JS minification (a fork of UglifyJS that supports ES6+).
• SWC / esbuild: Next-generation minifiers written in Rust and Go, offering 10x-100x performance improvements over JS-based tools.

Regex-based minifiers can break code if not careful:

• Strings containing comments: If you have a string let url = "http://example.com";, a naive regex minifier might see // and delete the rest of the line!
• ASI (Automatic Semicolon Insertion): JS relies on line breaks for semicolons. Removing all line breaks can cause syntax errors if semicolons are missing.
