Netflix JavaScript Talks - Async JavaScript with Reactive Extensions

Netflix JavaScript Talks - Episode 1
Async JavaScript with Reactive Extensions

In this talk, you'll learn how Netflix uses the Reactive Extensions (Rx) library to build responsive user experiences that strive to be event-driven, scalable and resilient. Learn the power of the Observable and how we've simplified our lives through the ability to filter, aggregate, compose and project data streams.

Join us while we discuss how Netflix uses Rx to:
- Declaratively build complex events out of simple events (ex. drag and drop)
- Coordinate and sequence multiple Ajax requests
- Reactively update the UI in response to data changes
- Eliminate memory leaks caused by neglecting to unsubscribe from events
- Gracefully propagate and handle asynchronous exceptions

This guy is a genius. He takes what could be a tough subject to teach, and turns it into first grade math. He really knows his stuff. I've read/seen other people trying to explain react, they don't even come close.

[FrontalLobotomized]

This is a great intro to RxJS. Well done Jafar.

[shaydohertybelfast]

Very good good presentation,  Matthew Podwysocki would be proud. Definitely got across the power of Rx!

[DanHaywood]

Excellent talk... who knew that Observable and Iterator design patterns were the same thing (more or less)?  Feel a bit dumb that I've only learnt about RX just now.

very nice rxjs overview with such an enthousiast speaker that make you want to work with

[JoeBuza]

Great presentation. Very easy to understand

[yapayzeka]

7:14 seems funny when watching 2021 :D

[DanielRamBeats]

Awesome speaker, makes it really clear

[lucasterable]

@22:11 retry(3) should be placed after concatAll() to work.

[zerkms]

Guys, is the definition for `getJson` from the example at 23:00 available somewhere? Curious how you implemented it to handle errors and support `retry`

[birthdayforfrances]

I don't get the "I haven't unsubscribed from an event stream in five years" comment. In the drag & drop example, the mouse-down subscription is presumably part of some widget. When you dispose of the widget, in his example you would leak the subscription. Only the mouse-move and mouse-ups subs are automatically disposed. How can he avoid unsubscribing from mouse-down? He says you listen forever, but that's not usually the case, as widgets come & go.

[FrankFang]

Why keyPresses.throttle but not keyPresses.debounce? Why? Does anybody know?

[ryanjacksonx]

There are a few factual flaws.
The speaker talks way too fast.

[peterkleinlich]

his style of speeking reminds me of south park timmy.

[muhammadalfaris]

This is Example, Rapper going to be a Programmer.

[mordwin]

Thank you very much! but speak slowly please
For some reason, all the tutorials of the best developers speaks so fast!
for goodness sake stop it!

[FredoCorleone]

Array.prototype.concatAll = function () { return this.reduce((a, b) => a.concat(b)) }
