[nwienert]

I once used RxJS for a dev tool platform, we had a use case where we had to take a tree-like structure of user data and recursively resolve all the async nodes.

Took it to the RxJS discord after a couple days of pounding my head on it. One of the creators was there and was super helpful.

We went back and forth on the problem at least 6 times each, with new attempts. He tried quite a few variations, but none ever worked.
