My engineer side is happy seeing how strong tooling enables such creative features with high assurances.
My futurist side is dreading the day Intel launches their first Javascript/WebAssembly-only processor.

I like JS the most.
It's flexible, lightweight, and omnipresent.
The only other mainstream language that gives me that feeling is Rust.
I'm using TypeScript and JavaScript interchangably.
I know JavaScript like the back of my hand, so TypeScript isn't telling me much new, but the static type checking allows me to keep less of that knowledge in working memory. Pretty awesome language!
I'm not even sure it would be a terrible idea, as we'd have a very interesting JS/WASM-like set of opcodes that we could target with _any_ compiler.
JS accidentally got part of the x86 execution model for float conversion baked into the spec. ARM added an instruction to mimic the old x86 one. It's potentially useful in some other contexts too.
