+Makes a `PUT` request to the passed URL.
+
+- Use `XMLHttpRequest` web api to make a `PUT` request to the given `url`.
+- Set the value of an `HTTP` request header with `setRequestHeader` method.
+- Handle the `onload` event, by running the provided `callback` function.
+- Handle the `onerror` event, by running the provided `err` function.
+- Omit the last argument, `err` to log the request to the console's error stream by default.

+```js
+const httpPut = (url, data, callback, err = console.error) => {
+  const request = new XMLHttpRequest();
+  request.open('PUT', url, true);
+  request.setRequestHeader('Content-type', 'application/json; charset=utf-8');
+  request.onload = () => callback(request);
+  request.onerror = () => err(request);
+  request.send(data);
+};
+```
+
+```js
+const password = 'fooBaz';
+const data = JSON.stringify({
+  id: 1,
+  title: 'foo',
+  body: 'bar',
+  userId: 1
+});
+httpPut('https://jsonplaceholder.typicode.com/posts/1', data, request => {

+}); /*
