        })
        .then(response => response.json())
        .then(json => {
          console.log('response: ' + JSON.stringify(json));
        })
    }
  </script>
</body>

</html>

Check the console to see the response

First you need to prevent the form from submitting, if not it will refresh the page. You can try this:

In Form

... <button id = "add_btn2" onclick = "New(event)" type = "submit">Submit</button> ...

In function

function New(e) { e.preventDefault() ...
As stated here JSONPlaceholder Guide, the resource will not be really created. Successful request will return a json object based on form-data you've sent. Just check your browser log, check if the responses just like what the documentation said.
