rescript

Just to be clear (and I now remember more details), I wanted to do bs.new with bs.send, but it wouldn't work. I am going to try what you suggested, but keep in mind I did go to the slack channel and tried asking this, none of their solutions looked like yours. Either way, intuitively @bs.new and @bs.send should be able to work together. https://github.com/BuckleScript/bucklescript/issues/2659

With Bucklescript/Reason you get typesafety, immutability, performance and small codesize: >Now we compare the runtime performance: BuckleScript Immutable Map: 1186ms Facebook Immutable Map: 3415ms We also compare code Size: BuckleScript (Prod mode): 899 Bytes Facebook Immutable: 55.3K Bytes source: https://github.com/BuckleScript/bucklescript/wiki/Why-buckle...

This sounds really cool, and it's exciting to see Elm come along! I always feel like Bucklescript and the Ocaml ecosystem doesn't get enough love when Elm crops up. Bucklescript has been doing aggressive dead code elimination for some time, and comes with the full type system of ocaml — plus easy JS interop: https://github.com/BuckleScript/bucklescript/wiki/Why-buckle.... As Elm develops I'm finding it harder and harder to choose between bucklescript/ocaml/reason and Elm. It's awesome to have all of these modern tools to work with on the frontend.

Some examples of "transpilers" targeting Javascript but writen in other languages: https://github.com/google/closure-compiler https://github.com/BuckleScript/bucklescript https://github.com/fastpack/fastpack Seems like on the average it does offer a boost in performance. And there is some aditional work providing javascript parsers for rust (which you could build tools like babel on top of): https://github.com/dherman/esprit
