Can you explain the concept of a promise interface in angular JS?
Furthermore, what exactly is a $q constructor?
In which scenarios are these functionalities utilized and how do they differ from each other?
I have looked into multiple resources but still couldn't grasp the distinction. Any suggestions or tips on where to find more information?
Exploring the concept of promise and $q:
A promise is a unique Object designed to handle asynchronous tasks, either pre-built or custom-made by us. The term "promises" signifies that we are assured of receiving a result at a later point in time. For instance, an HTTP call may finish in 200ms or 400ms, with a promise executing upon resolution.
A promise operates in three stages: pending, resolved, or rejected. By utilizing $q within Angular, we have the ability to create our own promises. However, it is beneficial to first understand how to generate one using the ECMAScript2015 Promise Object.
