Question

How do you perform error handling in observables?

Answer 1

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)}

});
