How do I handle asynchronous errors in Angular?

In Angular, you can handle asynchronous errors using RxJS operators like catchError and try-catch blocks in async functions.

Can you give me an example of using catchError?

Sure! You can use catchError in your service like this: return this.http.get('api/data').pipe(catchError(error => { console.error(error); return throwError(error); }));.

What about handling errors in a component?

In a component, you can subscribe to the service and handle errors in the subscription like this: this.myService.getData().subscribe(data => this.data = data, error => this.handleError(error));.

Is there a way to globally handle errors in Angular?

Yes, you can create an ErrorHandler service that implements the ErrorHandler interface to handle errors globally.
