An example of an AI chatbot conversation about real-world applications of promises in JavaScript.
What are some real-world examples of promises in JavaScript?
Promises in JavaScript are used to handle asynchronous operations. For example, fetching data from an API is a common use case.
Can you give me a specific example of using a promise with an API?
Sure! When you use the Fetch API to get data, it returns a promise. You can use .then() to handle the response.
What happens if the API call fails?
If the API call fails, the promise is rejected, and you can handle the error using .catch().
Are there any other use cases for promises?
Yes, promises are also used in file handling, database queries, and any operation that requires waiting for a result.
