As an Angular developer that has spent many hours playing Factorio I am your target demographic. This is very cool and creative thanks for making it.

It’s awesome that you used Factorio to explain RxJs. It would be awesome to see a few more examples in Factorio.

This video is definitely the best about the observavble concept!

*Awesome* stuff Josh. This is gonna be invaluable for people who learn in a more visual sort of way. This is a great way to demonstrate certain things 🔥

Wow Josh, I really enjoyed the way you explained the concepts of Reactive Programming. I am thankful for your existence.

God tier video! I wish there would have beeen videos like this when I was starting with Rxjs few years ago

I love your examples and how you explain RxJS. It's become a go-to resource for me. I don't build front-end applications much these days, but I do have a passion project that I want to build, and I'm thinking of using Angular, just to learn RxJS better. I know signals are a new thing, but I'll stick with RxJS for the learning experience. I could easily build the project using React/Next, but I know those libraries so well, it wouldn't serve as any learning experience.

Absolutely interested in something like that. You always explain things easier than anyone else man! Thank You

I loved RxJS now I want to play Factorio! Nice video, Josh.

For the movies example, what will happen if the movies is not yet fetched but there is already changes in the reactive form (seachTerm)?
Based on my understanding (correct me if I'm wrong), the code inside the pipe (i.e. map), is only triggered when there is already data that is passed for all streams. So in my example above, if the movies are not yet fetched, and the searchTerm has already an initial value, the map function will still not be executed since movies is not yet fetched (no value yet).

Mental Model: The Subscriber should not pull the data - It should just hold a box ready to be filled with data - The Subscriber is passiv it is not pulling data - the data is pushed at it - pushed into the box! Otherwise cool sample!
