Vite uses esbuild internally which lacks decorator support

I see you working on decorators and just wanted to let you know vite uses esbuild internally and consequently does not support decorators. Vite becoming the defacto devtool, this may pose a major hurdle for adoption.

That's a savvy thing to worry about, but I think we're ok.

Decorators work well using Typescript and esbuild and vite.
And @reactively decorated Typescript classes can be used seamlessly from Javascript.

If someone wants to write classes with reactive properties in Javascript using esbuild or vite, there are three options:

1. configure esbuild to compile Javascript as Typescript (as @evanw suggests in the esbuild issue above.)
2. manually add get/set accessors in your class backed by a hidden Reactive object. (That's all the decorator library does)
3. build a convenience library to make get/set accessors in Javascript. (contributions welcome!)
