What do you think about RxJS ?

Hi fellow WebDevs,

A friend of mine is pushing me to learn this JS library called RxJS (for a React project if that matter). Seems to me a really Angular-esque way of thinking and, from a first look, really abstract concepts to discover. I feel like it's a complicated way to do things that I'm already able to do with other tools. So what is your experience with it ? What are the real benefits ? Thanks
