**The Official JavaScript Reference: MDN**

Ever need to look up a JavaScript function or know what properties a built-in object in JavaScript has? If so, your first stop should be the [JavaScript Reference on the Mozilla Developer Network](https://developer.mozilla.org/en-US/docs/Web/JavaScript), or MDN. It is the [official JavaScript reference](https://blog.mozilla.org/blog/2017/10/18/mozilla-brings-microsoft-google-w3c-samsung-together-create-cross-browser-documentation-mdn/) for the [JavaScript language](https://developer.mozilla.org/en-US/docs/Web/JavaScript) and [APIs on the web](https://developer.mozilla.org/en-US/docs/Web/API).

As tips are posted here, you’ll notice that many will include a link to their respective documentation on MDN. Those links will provide much more information about a topic than the tip will, so it’s recommended to use those links to gain more information.
