What are common mistakes in promise chaining?

What are some common mistakes people make when chaining promises in JavaScript?

One common mistake is not returning the promise from the previous .then() method, which can lead to unexpected behavior.

Can you give me an example of that?

Sure! If you have a .then() that performs an asynchronous operation but doesn't return it, the next .then() won't wait for it to complete.

What happens if I forget to handle errors in promise chaining?

If you don't handle errors, any rejection in the chain will skip to the nearest .catch(), potentially leaving some promises unhandled.

How can I properly handle errors in promise chaining?

You can add a .catch() at the end of your promise chain to handle any errors that occur in any of the previous promises.
