What does the fetch API return if the request is successful?

The fetch API is designed to work asynchronously, making network requests easy to handle in JavaScript. When a request is successful, the fetch API returns a promise that resolves to a Response object. This Response object encompasses a wide range of information about the response received from the server, including status codes, headers, and the actual body of the response data.

The promise resolution allows developers to use methods like .then() to access the Response object, enabling them to handle the response efficiently without blocking the execution of other code. From this Response object, you can further manipulate the data, such as converting it into JSON, text, or other formats depending on the requirements of your application.

In contrast, the other options do not accurately reflect the behavior of the fetch API. The raw data in string format would not be returned directly; instead, it must be extracted from the Response object. An object containing the request headers is not a standalone return of the fetch API, as headers are part of the Response object. Lastly, providing a direct link to the API documentation is not part of the fetch API’s functionality; it simply deals with network requests and responses. Therefore, the promise that resolves to a Response object is the correct and comprehensive outcome of a successful fetch call
