|
| Edit: also, you should listen to "A study in Keith", it's a
| damn good piece. You can follow along as Andrew tweaks the
| grammar/Markov chains that make up the music, but it isn't
| necessary. The music starts at 1:56 (since the piece is written
| from scratch, there are a couple minutes of silent video while
| the author sets up the initial code).

|
| The challenge for a live coding browser environment is proper
| partitioning of the environment running the editor from the
| environment running code under development. The JavaScript
| environment in the browser is not multithreaded, so if the code
| under development hangs forever (and thanks to the halting
| problem, you can't guarantee it won't), you'll have a bad time
| because you can't access your tools to stop the code or modify
| the behavior.
|
| However, that doesn't mean it's impossible. There are multiple
| avenues I would suggest exploring that might ameliorate that
| problem (web workers, wasm, possibly iframes).
|
| As for the question of running racket in the browser in
| general, there are options.

| Well, there's WebWorkers. They're a bit limited due to the
| whole message passing thing but still quite powerful.
|
| Aside from that: could whomever downvoted the person above me
| explain what's misinformative about their comment?
