Chapter 8

1. A promise is an object that represents the result of an asynchronous operation. The use of promises simplifies the code when performing asynchronous calls.
2. The fetch API provides the fetch() method that you can use to make asynchronous network calls using JavaScript.
3. When using the REST API, it is recommended that you use the useEffect hook function if the request is sent after the first render.
4. You can access the response data using the promises with the fetch() method. The data from the response is saved to the state and the component is re-rendered when the state changes.
