#69 Creating & Using an Observable | Understanding Observables & RxJS | A Complete Angular Course

In the last lecture, we theoretically understood what is an observable and when we can use it to handle asynchronous data. In this lecture you will learn how you can create an observable and how to use the data emitted by that observable.

Clear Explanation!

[@VasilDimitroff]

Great tutorial! Will you create more lectures for RxJS, for example with HTTP requests like in the real app?

[@igorr4682]

I've yet to come across a video tutorial on this subject that doesn't rely on the ubiquitous example of Observables. One would think there are numerous real-world scenarios demonstrating their application.

[@RAVINDERSINGH-ht6pl]

Can we think observable as a container between subscriber and data source and can manipulate the data according to requirement before a subscriber can consume it.

Learnt react for web development fresher job and got one (currently on training) but realised i have to work with angular+typescript ;(

Mr. Manoj, I want ask question:
I can replace the lifecycle hooks to rxjs in some cases?

[@procademy]

How do you want to replace RxJS with angulars life cycle hook?

[@tomail1167]

The question is another way: Can I replace lifecycle hooks like "ngOnInit" and use "rxjs" in some cases?@@procademy

[@procademy]

@@tomail1167 You cannot avoid lifecycle hook methods to be called. They will certainly get called whenever a new component or a directive gets initialized. You may or may not use RxJS operators or observable in those lifecycle hooks.
