I did consider using the Node.js streams at one point but they support a lot of legacy edge cases and are more relevant for I/O than just a simple event stream (which was my use case). My stream library is less than 100 lines of code and only supports asyncIterator interface; also, it supports multiple concurrent consumers; each consuming at its own pace.
