# Understanding Asynchronous JavaScript: Callbacks, Promises, and Async/Await

Asynchronous programming allows JavaScript to perform long-running tasks like API requests and file operations without blocking the main thread. Modern JavaScript offers three common ways to handle asynchronous code:

## Callbacks

Callbacks execute a function after another function completes. While simple, deeply nested callbacks can lead to "callback hell."

## Promises

Promises provide a cleaner way to handle asynchronous operations using `.then()` and `.catch()`, making code easier to read and maintain.

## Async/Await

`async` and `await` build on Promises, allowing asynchronous code to look and behave more like synchronous code while simplifying error handling.
