Comparison of CoffeeScript, TypeScript, and Dart as JavaScript alternatives. CoffeeScript offers Ruby/Python syntax with code reduction; TypeScript is strict superset with optional typing and IDE support; Dart includes VM for server apps and optional typing with Java-like syntax. All three improve function syntax.
