A promise is an object representing the eventual completion or failure of an asynchronous operation.
Promises are used to handle asynchronous operations in JavaScript.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained using .then() to handle success and .catch() to handle errors.
Example: new Promise((resolve, reject) => { setTimeout(() => resolve('Done!'), 1000); });
promise.all is a method in JavaScript that takes an array of promises and returns a single promise that resolves when all of the input promises have resolved.

If any of the input promises is rejected, the returned promise is rejected with the reason of the first rejected promise
A callback is a function passed as an argument to another function to be executed later.
Callbacks are commonly used in asynchronous programming to handle tasks that take time to complete.
