Promises and observables are related but operate differently, just as a single string relates to an array. Promises represent a single operation, there is nothing wrong with the abstraction itself. As for the errors, I see what you mean. But at the same time this is an issue with trying to write async operations with sync constructs, something all "old" languages need to do. Async/await is a pattern that does that in languages that can't do it implicitly by requiring an explicit declaration. You don't need to write try/catch with async/await. You will get the exception propagated through the stack automatically.
