Are there any languages which actually support these modern features? e.g. better exception handling, 64bit, tail calls etc. Seems they are all way behind?

Anyone know a language that compiles to WASM v3?

Agree. If you carefully program something without tons of crap 3rd party libs in something like SolidJS im sure you could get it “native feeling” too

I’ll add I’ve worked on large scale RN apps used by millions per month. And the performance is awful. In fact I don’t think it would be possibly to make an advanced price chart like Tradingview for example, which runs perfectly well on a mobile.

Carefully re-exported and parsed to be small, clean, consistently sized and colorable.
