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, or MDN. It is the official JavaScript reference for the JavaScript language and APIs on the web.
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.
