How do you perform error handling in observables?
You can handle errors by specifying an error callback on the observer instead of relying on try/catch which are ineffective in asynchronous environment.
For example, you can define error callback as below,
myObservable.subscribe({next(num) {console.log('Next num: ' + num);},error(err) {console.log('Received an errror: ' + err);},});
