I love JavaScript, but also recognize when some other things are better (in the useful, pragmatic, non-edgy, non-trendy sense). Bucklescript/reasonML seem to be a way to use something better and keep what I like about JS without starting at zero in the job market or ecosystem. Specific example: if reasonML gets big enough then all react jobs are potentially reasonML jobs. In the bigger picture, purescript/elm/bucklescript/reasonML/clojurescript all have one problem. There's a lot of hype about how much better they are, but also the job market for them is nearly empty. This makes it difficult to justify spending a lot of time evaluating them before the jobs exist. I end up using flow or typescript in the short run.
