Laravel Examples
The differences between observable and promises are:
- Observable is a more powerful way of handling HTTP asynchronous requests. Whereas, A promise handles a single event when an asynchronous operation completes or fails.
- An observable is like a stream which allows passing zero or more events where the callback is called for each event. Whereas, A promise eventually calls the success or failed callback even when you don’t need the notification or the result it provides anymore.
- Observable works with multiple values for a particular time. Whereas, Promises works with and even returns a single value at a time.
- Observables can be canceled. Whereas, Promises cannot be canceled.
- Observable supports map, filter, reduce and similar operators. Whereas, Promises have more readable codes with try/catch and async/await.
- In observable, one operator ‘retry’ can be used to retry whenever needed. Whereas, Promises cannot be retried. A promise should have access to the original function that returned the promise in order to have a retry capability.
