After one year of OCaml/ReasonML and after that one year of TypeScript, I will not go back to Reason. 1. TypeScript has a better (more practical) type system (for the task of writing a WEB UI and interop with JS). 2. TypeScript is actually usable by people who do not have a PhD in type theory. 3. TypeScript has tools. This is a huge difference. 4. It's faster and cheaper to actually develop a product in TS than in Reason/OCaml. 5. Yeah, TS lets through more bugs, but it's actually just a small blip on the radar. In practice, TS makes it quite possible to get all of the benefits that OCaml claims without actually paying any real price. edit: formatting edit2: I still do use and love OCaml (on the backend), just not fooling myself I can actually ship a real (and big) web UI project using it.
