Assembly script is pretty interesting as a language. It's close enough to type script that the transition from that should be relatively easy for people already using that. And performance wise it gets them a lot of benefits.<p>There are a lot of other languages coming to wasm. It looks like garbage collection is stabilizing. E.g. jetbrains released an experimental wasm compiler for Kotlin recently that uses that. Currently that only works if you launch Chrome with some experimental flags to enable the feature. But at some point that will be generally available there, and in other browsers.<p>So, whether you are using C#, Kotlin, Swift, Crystal, or any other garbage collected modern language, chances are there will be a wasm compiler for it soon (if not already) and rich ecosystem of libraries and tools. I see this as a matter of time. Right now it's all a bit cutting edge. So, the whole space is dominated by languages not in need of garbage collection (C, C++, Rust, etc). However, that will change pretty soon.<p>E.g. Swift and Kotlin are already used for modern UI development on mobile. Using those languages in a browser makes total sense. Kotlin actually has a js transpiler and there are some Kotlin specific web frameworks that I've used. With wasm and the inevitable emergence of new UI frameworks targeting wasm and browsers, there might be a little renaissance in web ui development. Things like Figma prove that web uis don't have to be laggy, limited, and driven by css & dom trees.
