Understand JavaScript Promises and how they help handle asynchronous code.
Description:
Promises help handle asynchronous operations, replacing callback-based programming.
Explanation:
A promise represents a value that will be available in the future. It has three states: pending, resolved, and rejected.
Example:
const myPromise = new Promise((resolve, reject) => {
setTimeout(() => resolve("Promise resolved!"), 2000);
});
myPromise.then(result => console.log(result)); // Output after 2 sec: Promise resolved!
