### httpPut 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(password); httpPut('https://website.com/users/123', data, request => { console.log(request.responseText); }); // 'Updates a user's password in database' ```
