It supports most Racket data types (fixnums, flonums, hash tables, structures), tail calls, multiple values, and exceptions, but lacks continuations, modules, and multi-threading. A JavaScript FFI enables DOM, Canvas, MathJax, XTermJS, and JSXGraph integration. The compiler uses the standard Racket expander with a NanoPass-based middle-end and generates folded WebAssembly S-expressions. Examples include a MathJax editor, Matrix rain effect, Scheme REPL, pict library port, and Space Invaders game. Future plans include module support via linklets, complex numbers, bignums, and potentially continuations through CPS transformation. ## Full article daily.dev links to this article rather than hosting it.
