JavaScript Promises Explained Simply
A promise is an object that may produce a value sometime in the future. Either a resolved value or a reason that it’s not resolved (e.g., a network error occurred).
const price = Promise.resolve(20);
price
.then((amount) => amount * 2)
.then((total) => {
console.log(total);
throw new Error("Payment declined");
})
.catch((error) => {
console.log(error.message);
