Out of curiosity, how is that better than using Rust? My personal intuition is that by using a compile-to-JS + Node, you lose performance (Node.js is good for I/O, but not great for anything CPU-bound), plus combining Node.js and compile-to-JS is not too easy, if the compiler is not designed specifically for it (typically if it's not CPS-based). In addition, if you intend to use static typing on generated JS, I suspect that you are going to lose plenty of information.
