What are the best practices for writing asynchronous code?

When writing asynchronous code, it's important to use clear naming conventions, handle errors properly, and avoid callback hell.

Can you explain what callback hell is?

Callback hell refers to the situation where callbacks are nested within other callbacks, making the code hard to read and maintain.

How can I avoid callback hell?

You can avoid callback hell by using Promises or async/await syntax, which makes the code more linear and easier to understand.

What are Promises and how do they work?

Promises are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value.
