After attempting many courses about Angular, TypeScript, NgRx and RxJS, I can say that the Angular Master Bundle is the Greatest Of All Time!

Enea Jahollari

Front-end Developer

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!

Jared Hensley

Frontend Engineer

Very clear and concise tutorials. This really helped my understanding of various operators in the RxJS library.

Robert Hanson

Developer

If you want to learn RxJS for your professional career then you are in the right place. Very much worth the investment.

Mohammad Abdul Aziz

JavaScript Developer

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!

Attilio Urbani

Software Engineer

Got accepted for my first dev job a week ago! Not sure I'd have made it without these courses. My chances would've been lots slimmer without Ultimate Courses!

Mateusz Sapielak
