Off topic: why not support a strict subset of typescript to be compiled to native? This can be a great way to get everyone to use it build small applications I think.

goose.icu•32 days ago

It supports both JS and TS as input natively, you can just use a subset and I'll be as good as if it only supported it :)

andrewvijay.bsky.social•32 days ago

Ok fair enough

Are there any hidden-class like optimizations available so that objects don't have to be maps?

Do class fields get slots instead of map lookups?

goose.icu•32 days ago

Yes for builtin types (arrays, etc), not yet for class fields but should be possible.

I'm curious what kind of hidden-class optimizations could even look like in an AOT world. I wonder if there are papers on this.

Classes being a lot faster than plain objects would be interesting. I already use them a lot, but that'd be more pressure to.

The SharedStructs proposal has a bit of this. The class shape is fixed at declaration time, might be something AOT tools could leverage

goose.icu•32 days ago

Definitely interested in that proposal. I have one feature in the compiler which is kind of like hidden classes but more generic, I should write up about it some time.

I wonder if you could support Object.freeze({...}) at compile time to have fast objects?

gordon.bsky.social•32 days ago

my kingdom for fast frozen objects

goose.icu•32 days ago

Definitely could be a thing
