How do I fetch JSON from the server using Fetch API?

To get JSON from the server using the Fetch API, you can use the response.json() method. The response.json() method reads the data returned by the server and returns a promise that resolves with a JSON object. If you are expecting a text, call the response.text() method. The response.json() method returns a promise, which we need to chain another then() call to wait for that promise to complete. In this JavaScript get JSON with Fetch API example, we retrieve a JSON from ReqBin echo URL. Click Execute to run the JavaScript Fetch JSON Example online and see the result.
