+<p>Вы можете создать новый экземпляр объекта <code>Response</code> используя конструктор {{domxref("Response.Response()")}}, но скорее всего вы столкнетесь с объектом <code>Response</code>, как результат какой-нибудь API операции — например, service worker {{domxref("Fetchevent.respondWith")}}, или {{domxref("WindowOrWorkerGlobalScope.fetch()")}}.</p>

+
+<p>In our <a href="https://github.com/mdn/fetch-examples/tree/master/basic-fetch">basic fetch example</a> (<a href="http://mdn.github.io/fetch-examples/basic-fetch/">run example live</a>) we use a simple <code>fetch()</code> call to grab an image and display it in an {{htmlelement("img")}} element. The <code>fetch()</code> call returns a promise, which resolves to the <code>Response</code> object associated with the resource fetch operation.</p>
+
+<p>You'll notice that since we are requesting an image, we need to run {{domxref("Body.blob")}} ({{domxref("Response")}} implements Body) to give the response its correct MIME type.</p>
+
+<pre class="brush: js notranslate">const image = document.querySelector('.my-image');
+fetch('flowers.jpg').then(function(response) {
+  return response.blob();
+}).then(function(blob) {
+  const objectURL = URL.createObjectURL(blob);
+  image.src = objectURL;
+});</pre>
+
+<p>You can also use the {{domxref("Response.Response()")}} constructor to create your own custom <code>Response</code> object:</p>
+
+<pre class="brush: js notranslate">const response = new Response();</pre>
+
+<h3 id="Ajax_запрос">Ajax запрос</h3>
+
+<p>Здесь мы с помощью функции doAjax вызываем PHP скрипт, который генерирует JSON строку, и возвращает распарсенный JSON в виде JavaScript объекта. Также реализована простая обработка ошибок.</p>
+
+<pre class="brush: js notranslate">// Функция, которая делает Ajax запрос
+const doAjax = async () =&gt; {
+    const response = await fetch('Ajax.php'); // Генерируем объект Response
+    if (response.ok) {
+        const jVal = await response.json(); // Парсим тело ответа
+        return Promise.resolve(jVal);
+        }
+    else
+        return Promise.reject('*** PHP file not found');
+    }
+}
+
+// Вызываем doAjax и выводим результат в консоль
+doAjax().then(console.log).catch(console.log);
