Webinar: Observables For All

Observables vs. Promises

In this section, we are going to discuss how observables compare to promises.

Here is the link to the stackblitz referenced in the video above: https://stackblitz.com/edit/observables4all

How promises and observables are similar:

  • They both have a simple constructor that only takes one parameter
  • They both inject what you need to handle success or a failure scenario
  • You can subscribe to either one of them using the .then for a promise or .subscribe for the observable method
