JSX

[mbostock]

Framework has some nice support for JSX. It’s implemented using esbuild, which is a challenge since we currently do transpilation client-side. Perhaps we could use Babel (too big?) or acorn-jsx (which is nice because we already use Acorn for everything else).

There’s also the question of whether we want the same display semantics (where calling display replaces whatever was previously displayed rather than displaying something new). That seems a little quirky in retrospect…

I was looking at how Preact Playground works and supports JSX.

It uses sucrase "Super-fast Babel alternative" (then @rollup/browser), which has it's own nice client-side playground there.

Preact playground runs it all in a worker here.

Not sure how this compares to acorn-jsx or overall fit.
