One thing to remember is that Reason and BuckleScript are rather small projects, with not that many people employed to work on them. Their combined 'manpower' is not that much more than Elm's right now.
What they are cleverly leveraging is the twenty years of solid type theory (a sound type system), language design (more powerful pattern-matching, functions, syntax sugar), and engineering practice (the OPAM ecosystem) that has gone into OCaml.
This is why Reason/BuckleScript are able to punch above their weight class.
