Especially compile speed, and especially if the program is composed of libraries that don’t all need to be compiled every time. There is something super nice about editing JS and being able to see the change immediately, but I’d still trade that off for some type safety in a “compile to JS” language that wastes a second of my time per compile. The other point about compile speed is it doesn’t affect the end user (if we are talking about source code compilation not JIT)
