When chaining promises, always return the promise from the previous .then() to ensure proper sequencing.

Can you give me an example of promise chaining?

fetch('url')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

What should I avoid when using promise chaining?

Avoid nesting promises, as it can lead to callback hell. Instead, chain them to keep your code clean and readable.

You can handle errors by adding a .catch() at the end of your chain, which will catch any errors from the previous promises.
