Error & Completion of Observable | Observables | Angular 12+

In the last lecture we learned that an observable is a way of handling asynchronous data. It emits data. Apart from data, an observable also emits an error and a completion signal.

In this lecture you will learn how to handle errors returned by an observable and how to execute some logic when an observable emits a complete signals.

Since the old way of subscribing an observable( using callback) is deprecated, I am implementing using new ways i.e.
subscribe({
next(value) {
console.log(value);
this.isLoading = true;
},
error(err) {
console.log(err);
},

But i am unable to access my class variable inside next/error method as this is now referring something else.. can you please suggest how can i access this to use class properties? Although when i set strict mode to false the issue resolved can anyone please help me with concept?

How do you handle the error randomly since we are emitting data in a chunk .. how do we know when to check if the error is occurred ?. Does it mean we have to check error method in every next method . Please explain

subscribe keyword looks deprecated, how can we resolve it ?

looks like new Angular 13 and up has deprecated the subscribe method, now you have to use with the object subscribe({next:(), error:(), complete:()})
