### ⭐⭐⭐⭐⭐ 







  
  
    Good Introduction to RxJS, Reactive Programming, and Angular's Reactive Forms
  

*by L***Y on Reviewed in the United States 🇺🇸 on February 24, 2019*

I'm an Angular developer, and I use RxJS a lot in my development. I picked up this book after having seen Randall at a couple conferences, and I wanted to see his take on things.This isn't a thick book, but it gives really good information on Reactive programming, RxJS, Angular, and Angular's Reactive Forms. It doesn't go into ngrx and Angular performance much, but the introduction it gives for both is solid.In my development, I really appreciate the power of reactive development and Reactive Forms, and it was good to see them taken seriously here (I think Reactive Forms in particular are underappreciated).The only part of the book (besides a line and hint here and there) that was new for me was the last chapter on writing a game in canvas. Pretty cool stuff.I teach classes on Angular through my company's Angular Boot Camp, and I'm going to suggest this book to future students as a resource for good Angular and web development.

    Worth studying if you do anything async in js
  

*by O***S on Reviewed in the United States 🇺🇸 on July 19, 2019*

RxJS is a huge library that's very scary to approach. I like how the book start presents RxJS operators in a way that builds an understanding of Observables and Subjects, followed by ways to use those types with some of the operators.When I was first introduced to RxJS, it was through Angular's Tour of Hero's tutorial which glosses over RxJS and I struggled with Observables early on. I wish this book had been around at that time, and after reading this book, it's helped me understand async javascript better and how to use Observables in different ways.If you think Promises, Generators, and async/await are fascinated, you should give this book a try as it'll likely blow your mind.It's also nice that each concept is provided through the lens of some application that you can build and experiment with, so you can be more engaged.
