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)}
    });
