The best RxJs video I've ever seen. Simple, clear, logical without unnecessary rocket science.❤

Deborah is posting Angular and RxJS videos on YT! Cheers from Brazil, teacher! YAY!

[sethell]

I was going insane trying to understand Observables and your explanation finally flicked the lightbulb on. Thank you!

[madoudev]

This is hands down the best explanation I've encountered. Everything now fits in place. Absolutely underrated channel! Thank you so much!

[hawkcs]

You are a legend Deborah, I learned Angular thanks to your videos. Thank you!

[wilsonbarbosa]

Excellent video! It came in handing, since I'm learning Angular atm. Great work, by the way! Unfortunately it's not that common to see woman doing tutorials and videos like this in tech, big ups to you lady! God bless!

I love the way you make complex things easy to understand. That's the best video on RxJS. Thanks for all the hard work you do to make these videos.

I am familiar with almost all of these. But i still watched it. And got valuable information info.
I love to watch whatever you explain.
Thanx

I 've been learning Angular since 2018, it was a complete change of paradigm of how to develop programs. Many other tutorials show different ways to do the same things, too confusing. This video clarifies a lot for me. Thanks million!

[clintonlobo]

Whole heartedly agree with other comments. Thank you, @Deborah Kurata, for taking the time and energy to explain something not so easy to understand, for free on YouTube. Even after purchasing Udemy tutorials, I did not get a clear understanding. Finally, I found your channel and RxJS concepts seem to finally fall into place !

[ayyappahemanth]

Omg! The explanation makes it look very easy and it makes me feel i know everything way before. Thanks for the video, keep doing more.

[semperfiArs]

[jurijdevelopment]

Thanks Deborah for the Rxjs course. This is the best one I've come across.

DK is the best at explaining complex topics in plain English. I watched all of her videos in Pluralsight and attended her sessions at conferences.

[bushbuddyplatypus]

Deborah you really know how to simplify things. Thanks

[aytidareads]

Hey Deborah! Your video really helped me grasp some RxJS concepts I've been struggling with for years. Thanks for breaking it down in such an easy-to-understand way!
