Racket's interactive mode encourages experimentation, and quick scripts
easily compose into larger systems. Small scripts and large systems both
benefit from native-code JIT compilation. When a system gets too big to
keep in your head, you can add static types.
Extend Racket whenever you need to. Mold it to better suit your tasks
without sacrificing interoperability with existing libraries and without
having to modify the tool chain. When less is more, you can remove parts
of a language or start over and build a new one.
Whether you're just starting out, want to know more about programming
language applications or models, looking to expand your horizons, or
ready to dive into research, Racket can help you become a better
programmer and system builder.
