How does rsvp.reject work?

rsvp.reject is a function in the RSVP.js library that returns a new rejected Promise with a specified reason.

When rsvp.reject() is called, a new Promise is created and immediately rejected with the specified reason. The rejected Promise can then be used with .catch() to handle the error case.

const RSVP = require("rsvp");

const myPromise = RSVP.reject("Something went wrong.");
myPromise.catch((error) => {
  console.error(error);
});

In this example, RSVP.reject() is used to create a rejected promise with the rejection reason of 'Something went wrong.'. The catch() method is then used to handle the rejection and log the error message to the console.
