See how terser/uglify remove dead code across versions. E.g. what it can or can not remove.

Unfortunately they are pretty primitive and don't meet all my requirements.

TODOs:

• Basic UI that takes input code and output minified code using terser
• Support options simple - take a JSON blob
• Support options advanced - let people enable/disable options using checkboxes
• Support multiple terser versions
• Support sharing
• Clean old shared links
• Various UI improvements
  • code highlight
  • prettify layout
  • default value in version selection dropdown
  • show spinner while initializing states from persistence
• Clean up TODOs in code
• Accept relaxed JSON object as configuration
• Persistence
• debounce user inputs
