There are a lot of programming languages that compile down to JavaScript. I used to be big into Dart, but lost interest when they became solely focused on Flutter.
I personally like using Haxe as it compiles to actual readable JavaScript (and, for fun, a bunch of other languages).
You can also do this with dart. I swear there was another “new” language which could also be compiled to JS as well.

Scala can also compile to JS.
