Feature request: Implement the Decorator Metadata proposal

[uinz]

I think esbuild should behave the same way as typescript when compiling decorators

ts playground

esbuild playground

This looks like a feature request for https://github.com/tc39/proposal-decorator-metadata, which is a separate proposal from https://github.com/tc39/proposal-decorators.

Thanks for your reply, you are right.
It was me who confused the two proposals.
esbuild is implemented for the tc39 standard.

Reopening this issue because it should probably still be implemented. I'm not sure why it's a separate proposal (e.g. if that means the committee is more unsure about it?) but TypeScript has already implemented and shipped it so it's not going away any time soon. I'm just not sure how ready it is to be implemented at the moment.
