| Here are my personal opinions as a long time Dart/JS/TS developer. - Dart had a lot of features before either JS or TS. Important features like cancellable promises or optional chaining are still missing (I know they might be coming soon). Also some nice quality of life features like named constructors. - As a superset of JS, Typescript has a lot of idiosyncrasies that might bother people. Personally I don't mind, but people new to web development often find Dart to be a friendlier experience, with fewer pitfalls. - To me, and this is very subjective, the TS syntax is uglier than either JS or Dart. The types get in the way and add noise to the code. I find Dart's and pretty much any other language's type declarations much cleaner. However, I have two very big problems with Dart that prevent me from using it as much as I'd like to. - JS interop is much much cleaner in Typescript/Flow. Every compiled-to-JS language that isn't a superset suffers from this. It's what prevents me from using ReasonML seriously too. - No support for JSX. I can't go back to writing nested createElement after using JSX |
But the main thing for me between TS and reason is exhaustive pattern matching is better in reason, it feels jacky in TS
could I use reasonml/js with flutter widgets and ignore dart?
