How do different async tools compare for web development?

What are the main differences between async/await and callbacks in JavaScript?

Async/await provides a more readable and synchronous-like structure, while callbacks can lead to callback hell.

Can you explain how Promises fit into this comparison?

Promises are a cleaner alternative to callbacks, allowing chaining and better error handling, but async/await is built on top of Promises.

Which one is better for handling multiple asynchronous operations?

Async/await is generally preferred for readability, but Promise.all can be very effective for running multiple operations concurrently.

Are there any performance differences between these methods?

Performance differences are usually minimal, but async/await can introduce slight overhead due to its syntactic sugar.
