Yes, and since typing is only at compile time, it's also missing some of the extremely convenient pattern matching syntax that I love from Haskell, Rust, Scala,

  I consider ReasonML and ReScript to be effectively dead since they split the community a few times now. I don't know anyone who's actually using either in production, except for their respective sponsors Meta and Bloomberg.

  Why is pattern matching not possible when types are removed after typescript is compiled?
  • dllthomas 4y ago
    That was my first interpretation as well, and I don't think there's actually any such technological limitation. But I think what was meant is that typescript's mostly committed to not changing runtime behavior of the JS that remains when you strip the types away, and while I we might disagree with that goal or with its application in this instance, I can at least see the flow of the reasoning and label it a matter of priorities.
