What are the benefits of promise chaining in JavaScript?

What are the benefits of promise chaining in JavaScript?

Promise chaining allows for cleaner, more readable code by avoiding callback hell. It also helps in handling asynchronous operations more effectively.

Can you give me an example of promise chaining?

Sure! Here's a simple example: fetchData().then(data => processData(data)).then(result => displayResult(result)); This chains multiple asynchronous operations.

How does it improve error handling?

With promise chaining, you can handle errors in a single .catch() at the end of the chain, making it easier to manage.

Are there any downsides to using promise chaining?

One downside is that if a promise in the chain fails, it can break the entire chain unless properly handled with .catch().
