Understanding JS Promises

Question

I would like to get a deeper understanding of how Promises work internally. Therefore I have some sample code:

var p1          


        

Answer 1

Please check the below example regarding how promises works:

The Promise object represents the eventual completion (or failure) of an asynchronous operation, and its resulting value.

console.log('person1: shoe ticket');
console.log('person2: shoe ticket');

const promiseGirlFriendBringingTickets = new Promise((resolve, reject) => {
	setTimeout(() => {
		resolve('ticket');
	}, 3000);
});

promiseGirlFriendBringingTickets.then((t) => {
	console.log(`person3: show ${t}`);
})

console.log('person4: shoe ticket');
console.log('person5: shoe ticket');
