-Here we see ` fetch``() ` taking a single parameter — the URL of a resource you want to fetch from the network — and returning a [promise](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). The promise is an object representing the completion or failure of the async operation. It represents an intermediate state, as it were. In essence, it's the browser's way of saying "I promise to get back to you with the answer as soon as I can," hence the name "promise."

 This concept can take practice to get used to; it feels a little like {{interwiki("wikipedia", "Schrödinger's cat")}} in action. Neither of the possible outcomes have happened yet, so the fetch operation is currently waiting on the result of the browser trying to complete the operation at some point in the future. We've then got three further code blocks chained onto the end of the `fetch()`:

     Here our friend [`create()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create) comes to the rescue again. In this case we are using it to create a new object and make it the value of `Teacher.prototype`. The new object has `Person.prototype` as its prototype and will therefore inherit, if and when needed, all the methods available on `Person.prototype`.
 
-2.  We need to do one more thing before we move on. After adding the last line, ` Teacher.``prototype `'s `constructor` property is now equal to `Person()`, because we just set `Teacher.prototype` to reference an object that inherits its properties from `Person.prototype`! Try saving your code, loading the page in a browser, and entering `Teacher.prototype.constructor` into the console to verify.

-The `Router` also provides route methods for all the other HTTP verbs, that are mostly used in exactly the same way: `post()`, `put()`, `delete()`, `options()`, `trace()`, `copy()`, `lock()`, `mkcol()`, `move()`, `purge()`, `propfind()`, `proppatch()`, `unlock()`, `report()`, `mkactivity()`, `checkout()`, `merge()`, ` m-``search() `, `notify()`, `subscribe()`, `unsubscribe()`, `patch()`, `search()`, and `connect()`.

-For example, the Django template system allows you to specify variables using a "double-handlebars" syntax (e.g. ` {`` { variable_name ``}``} `),  which will be replaced by values passed in from the view function when a page is rendered. The template system also provides support for expressions (with syntax: `{% expression %}`), which allow templates to perform simple operations like iterating list values passed into the template.
