embed REPL & canvas into teaching materials

[echeran]

Because CLJS is self-hosted (you can compile CLJS code using CLJS -- no JVM required), it is possible to have a webpage that runs its own REPL. Also, it is possible to embed Quil sketches in a webpage. So it should be possible to have a webpage with a REPL next to the Quil canvas that it controls.

The Quil homepage contains examples of sketches that run. You can edit and run your own sketches online, too.

The Quil creator has also written about understanding the CLJS self-hosting features:
