    What are the expected semantics of: get(url).then(v => JSON.parse(v)).catch(v => throw v); assuming that get() would succeed and fulfill its promise with invalid JSON, which would cause JSON.parse to throw an error.

        clarification, "hung promise" means that it remains hung after the get() promise fulfills and async has had a chance to settle.

        A throw inside a .catch() should re-reject, I thought.

        Arrow function implicit return doesn’t play nicely with throw, IIRC :/

        Should not matter - throw causes abrupt completion, unwinding w/o return value.

        yeah nothing to do with the return itself, just basic statement/expression mismatch for throw i *think*

        Throw should be an expression, imo. It’s weird that it isn’t.

        To me, the promise is attached to the request so if its 200 then promise fulfilled. Valid JSON is a separate issue and should have its own validation structure

        Even if not a 200, the promise still is fulfilled ??

        I would expect a syntax error if “throw expressions” are not supported in the JS engine, otherwise a rejected promise.

        We actually had this almost this exact issue. We were using fetch and response.json() was throwing an error. Took a while to figure out 😀

        I would expect an uncaught error, since it gets re-thrown within the `.catch()` and there's not an additional `.catch()`

        Then again if you simply return from inside a `.then()` (as opposed to `return Promise.resolve()`) you get a resolved promise... 🤔

        Compile error due to the throw in an arrow function. Otherwise it should be a rejected promise.

        Really looking forward to this answer, as I think it might be the solution to some (read: over 100k) errors we've been having 🙊

        Just realized that's a throw in a catch, so it's probably a fulfilled promise and a thrown error?
