My AJAX call keeps returning response object instead of the expected value

  function check_now(word)
    {
           var x =  $.ajax({
            url: "{% url 'checker' %}",
            data: {
                   'word': word,
                   'csrfmiddlewaretoken': '{{ csrf_token }}',
                    },
            async:false,
            type: "POST",
            dataType: 'json',
            statusCode: {
                 200: function (response) {
                      console.log(response.is_command);
                      return response.is_command;
                        }
                 }
        });
        return x;
    }

Expected result is a boolean. Output of console.log(response.is_command) is printed correctly as false. But returned value x is still an object. I can't access the is_command. How to access it?
