Jordan Walke, creator of React, talks at ReasonConf 2019 about the ideas behind ReasonML and how it extends React's programming model with OCaml. He also discusses why familiar syntax matters.
HN recommends it as the best introduction to Reason's motivations, straight from React's creator.

I'd highly recommend Jordan Walke's (creator of React) talk on the ideas behind ReasonML: React to the Future [1]. I think it's so cool that you can take the ideas of ReactJS - functional programming applied to UI - but then have a language (ReasonML [2]) that is essentially purpose built for it, with OCaml [3] powering it under the hood - a functional programming language that's been significantly invested in, both in academia and industry. And to be able to take React-the-Idea, compile it cross-platform, to native-code... and ship. - [1] Jordan Walke - React to the Future: this video - [2] [LINK] - [3] [LINK]
The long awaited 0.8.0 release from Reason React is out of beta! This includes a lot of the niceties of writing React but in a very fast, type safe language. If this is your first time hearing about Reason, watch a video from its creator (Jordan Walke, creator of React) to learn more: this video Fun facts about Reason: - exports TypeScript! If you have a TS project and looking for some extra speed & stability, you don't have to sacrifice type safety interop - It powers all of Messenger.com. The team put out a case study where they went from ~10 bugs a week to less than 10 a quarter by switching to Reason - It uses the npm / yarn ecosystem so you can use your favorite / current packages without looking for something new.
He's a Fullstack JS developer which is even dumber because he uses React which is basically the defacto JS front end framework. React is trending heavily away from OOP, it's creators heavily buy into FP, and most of the patterns in react are inspired heavily by FP. Functional components are now the way to go. ReasonML (a pure FP language) is react as intended and is the northstar of React. To learn more here is a video from Jordan Walke creator of React (and ReasonML): this video I recommend parent commenter to learn more about the very tools he himself works with before disparaging FP and himself.

Why ReasonML is a logical extension of ReactJS’ programming paradigm. this video “Typing the untyped: soundness in gradual type systems” by Ben Weissmann.

Jordan Walke, the creator of Reason (also the creator of React) said that syntax is unfortunately very important, because psychologically people want something familiar. I think syntax is totally superficial, but I’m also a human who interacts with other humans. And they do not think it’s superficial. The talk where he says this: this video
