Even in Node I found the rx* libraries to be a bad abstraction and slow. I tend to just have my own observable stuff as I only want a small feature set in that regard anyway.
Yes same. I write myself a nice typed pipe() [2], and a one-after-the-other promise queue[4] whenever I need it but that's it really. I use web streams a lot.
The most abstract I'm usually willing to get is using River [5] instead of array's map/filter/reduce.
There seems to be an absolute obsession over these libraries now though. I assume it's fueled by every frontend library pushing functional patterns. See Effect [1] for example, it's insane how much is piled on.
