I get asked this question a lot — I help maintain redux-saga.

I recently gave a talk where this question came up: https://youtu.be/uRbqLGj_6mI?t=2166

I’ve also imposed generators on a lot of colleagues.

I think they are mostly misunderstood and potentially in the realm of being “magical” — at least on the surface.

The reality is they are syntactic sugar on top of functions with recursive switch statements where each case is a yield point.

They aren’t that hard to grok — the syntax is mind bending. Having code that looks synchronous but behaves asynchronous is “magical.”

I think it does come down to that because everyone loves async/await even tho that’s just sugar on generators where each yield must be a promise.

Personally, I love redux-saga. It took me a little while to wrap my head around it (but 1/10th the amount of time as RxJS), but it is _really_ nice to be able to write complex async logic in synchronous-looking code that's also readable. (At least it was readable for me and the people on my team.) Whenever I had some weird async coordination problem that I needed to solve, I was _always_ able to solve it with redux-saga. I wish more people would use it.

I feel the same way which is why I decided to help maintain the project. Async flow control is very tricky even in js–land. Having watchers live inside of a while-loop is a powerful construct that lends itself to interest flow control patterns.

I'm also in the process of rebuilding redux-saga but without the redux part: https://github.com/neurosnap/starfx

It's still in alpha stage, but it is very reminiscent of redux-saga.

And then there's async generators...
