Example 5-1. Explicitly rejecting a promise

var rejectedPromise = new Promise(function (resolve, reject) {
	reject(new Error('Arghhhh!')); // Explicit rejection
});

rejectedPromise.catch(function (err) {
	console.log('Rejected');
	console.log(err);
});

// Console output:
// Rejected
// [Error object] { message: 'Arghhhh!' ... }
