> Is there any parallel there Of course. Promise is a monad, .then is more or less equivalent to the >>= operator and await makes it look more imperative-ish just like <- in Haskell. Note that in JS you'll need to be inside an async function to use await, just like in Haskell you'll need to be inside the do notation to use <-. Otherwise, you'll need to play with .then just like you would need to play with >>= in Haskell. About other languages, one way to achieve asynchronous behavior without having it implemented in the language is using ReactiveX (https://reactivex.io/ https://reactivex.io/). It's hard to understand at first, but it if you understand the IO Monad it becomes easy, as it's basically the same.
