What does the fetch () method return?
Consequently, what is fetch method?
The Fetch API provides a fetch() method defined on the window object, which you can use to perform requests. This method returns a Promise that you can use to retrieve the response of the request. The fetch method only has one mandatory argument, which is the URL of the resource you wish to fetch.
Then, what mandatory argument does the fetch () method take?
The fetch() method takes one mandatory argument, the path to the resource you want to fetch. It returns a Promise that resolves to the Response to that request, whether it is successful or not. You can also optionally pass in an init options object as the second argument (see Request ).
Fetch is a browser API for loading texts, images, structured data, asynchronously to update an HTML page. Therefore, if you are looking for maximum compatibility, you will continue to use Ajax to update a web page. If you also want to interact with the server, the WebSocket object is also more appropriate than fetch.
