What is the @ symbol in Javascript?
<p>I stumbled upon <a href="http://codereview.stackexchange.com/questions/10610/refactoring-javascript-into-pure-functions-to-make-code-more-readable-and-mainta">http://codereview.stackexchange.com/questions/10610/refactoring-javascript-into-pure-functions-to-make-code-more-readable-and-mainta</a> and I don't understand the answer since the user uses an @ symbol in a way I've never seen before. What does it do when attached to the if keyword? Can you attach it to other keywords?</p>
