After the RxJS courses I know much more than before about RxJS. I've learnt in a practical way how and when to use the powerful operators the library provides taking advantage from them in the daily work. Amazing!

I've been using RxJS in some capacity due to working within the Angular ecosystem. I'm still relatively new to the ecosystem and have managed to 'get by'. Well, not anymore. This course has helped demystify a lot of my initial confusion with reactive programming. Amazing course!
