A hopefully short and concise explanation as to how Clojure deals with Objects. If you already write Clojure, this isn't for you.
You know what an Interface is if you write/read Java or PHP 5+. In Clojure it might be called defprotocol.
user> (defprotocol IABC
(also-oo [this])
(another-fn [this x]))IABC
Instructions courtesy of @chancelionheart:
Access the Settings menu by clicking the Options icon in the upper-right corner of the browser window. It is the icon with three horizontal lines stacked on top of each other. Click on “Settings” near the bottom of the Options menu.
Under the “Search” heading in the Settings menu, click the "Manage search engines" button.
At the bottom of the Search Engines window that comes up, enter the following: Name: Use whatever you like (I used "Webster's Revised 1913+1928 Dictionary") Keyword: Also whatever you like, I just use 'd' for easy access. Url: http://machaut.uchicago.edu/?resource=Webster%27s&word=%s&use1913=on&use1828=on (replaces the search term with %s, what google chrome uses for the query)

| * VH and VW units can cause issues on iOS devices: http://caniuse.com/#feat=viewport-units | |
| * | |
| * To overcome this, create media queries that target the width, height, and orientation of iOS devices. | |
| * It isn't optimal, but there is really no other way to solve the problem. In this example, I am fixing | |
| * the height of element `.foo` —which is a full width and height cover image. | |

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.
