racket-mode

ional opportunity: there are still times when knowing how to do old-school list-processing is exactly what you need, and it's pretty fundamental data structures (e.g., singly-linked lists, trees), so we could consider it practice. :) BTW, one difference between modern Racket lists and Scheme's is that Racket's default pairs are immutable. This turns out to be useful for optimizations, as well as encourage a healthy amount of functional programming. Regarding #2, good point. I raised the WASM issue a couple years ago, and my thinking then (and now) is to build it for the forthcoming Chez backend, while getting plugged into the WASM standards work in the meantime. There are various ways to do JS with Racket (a big HTML5 Offline app of mine does it by generating JS and HTML from Racket), but WASM seems most promising. Regarding #3, if Geiser works for you, great. You might also take a look at Greg Hendershott's racket-mode for Emacs: https://github.com/greghendershott/racket-mode I appreciate that DrRacket's student-emphasizing IDE is very different than most IDEs, and it's missing some things I'd like, for editing many modules at once. If you're up to adding some features you'd like, there's an extension mechanism, and you can also do git pull requests to the DrRacket source itself. https://docs.racket-lang.org/drracket/extending-drracket.htm... https://docs.racket-lang.org/framework/index.html Regarding #4, there are Web frameworks, and the main Racket Web Server (which you don't have to use; you can also do things like SCGI or proxy another HTTP server implementation), and you can also whip up your own frameworks very rapidly in Racket unlike many languages. I'm hoping a couple startups use Racket to get to launch, and release the light frameworks that they make along the way. Regarding reader extensions, Racket has those, as well as a ton of great syntax extension mechanisms: https://docs.racket-lang.org/guide/hash-reader.html
