An async function always returns a promise, and the await keyword pauses execution until a promise settles, allowing you to write linear, non-nested logic that is significantly easier to debug. Rejected: The state indicating the operation failed.

Fulfilled: The state indicating the operation completed successfully. reject() let you create promises that resolve or reject immediately.
Understanding the Asynchronous Problem Before promises, managing asynchronous tasks like network requests or file operations led to "callback hell," where nested callbacks created deeply indented and fragile code. An async function always returns a promise, and the await keyword pauses execution until a promise settles, allowing you to write linear, non-nested logic that is significantly easier to debug.
Create Promise JavaScript Immediately: Instantiate Promises with resolve and reject
Pending: The initial state, indicating the operation is not yet complete. Modern Async/Await Syntax Built on the foundation of promises, async and await provide syntactic sugar that makes asynchronous code look and behave more like synchronous code.
