  • proposal-observable

    Observables for ECMAScript

    • RxJS is an implementation of observables which do not exist natively in JavaScript. There is a proposal for adding observables to the language, but it's only stage 1 and hasn't been active for years.

  • proposal-iterator-helpers

    Methods for working with iterators in ECMAScript

    • Native JavaScript also has async iterables which are also similar, but again, less powerful. The active iterator helpers proposal will help with that, adding RxJS-like operators to iterators, but these are still very limited compared to what RxJS has to offer.
