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,
javascript
myObservable.subscribe({
next(num) { console.log('Next num: ' + num)},
error(err) { console.log('Received an error: ' + err)}
});
