What are some real-world use cases of promises in JavaScript?
Promises in JavaScript are used for handling asynchronous operations. Common use cases include API calls, file reading, and database queries.
Can you give me an example of using promises with an API call?
Sure! When fetching data from an API, you can use the fetch() function which returns a promise. You can then use .then() to handle the response.
What happens if the API call fails?
If the API call fails, you can catch the error using the .catch() method to handle it gracefully.
Are there any libraries that simplify working with promises?
Yes, libraries like Axios and Bluebird provide additional features and simplify working with promises.
