I’ve been using RxJS 6 in Angular 6, and yeah, it’s been great. It’s also been a huge pain to wrap my head around.
The shifting API interface, the breadth of the library, and the lack of examples and explanations make it difficult to do anything other than the most simple examples. There’s also a mindset shift required that is ignored in any of the docs.
I thought about writing an intro, but a friend found this great one and it does the introduction thing better than I ever could, so check it out and let the author know that its awesome.
