There's some neat stuff in the Reason syntax, apart from the make-it-less-weird-for-those-coming-from-JS/Java/C#/etc., for instance: JSX[0] and named curried functions[1]. Both are fitting in really nice when doing FE dev't like with `react-reason`[2].
If you are interested in this, I recommend some talks. First one by Cheng Lou, a main contributor of Reason and FB employee on React Conf 2017[3]. And a talk by Sean Grove[4] on Reason in general.
With the power of FB behind this new techonolgy (they have currently written 25% of messenger.com in Reason), this might well become very big. A general purpose strongly typed functional prog lang, that has a vast ecosystem, now an approachable syntax, and compiles to both native and JS. Sounds good nuh?
