JSX namespace support

[wycats]

While React doesn't support JSX namespaces, they're explicitly part of the JSX spec. Is there a specific reason that esbuild doesn't parse namespaces?

Well React doesn't support them and I'm not aware of anything else supporting them either, so it's not clear to me how they are supposed to be translated to JavaScript. I can certainly parse them and turn them into a prettier syntax error if that's what you mean.

@evanw non-React JSX implementations could use them in their configured factories. I think the most natural thing to do would be to simply allow the syntax and pass it as a single colon-separated attribute name.

This change has been released by the way. It should work in version 0.8.36.

I'm somewhat curious about your use case. Was it something specific? Or just checking for compliance with the spec?

@evanw it’s for glimmer 3 POC, https://github.com/wycats/shimmer

@lifeart is correct 😄
