title: Parenthesis placing after function
body: <p>Which is the common best practice for where to place parenthesis after a function? I see at times <code>function ()</code> and I see <code>function()</code>. With parameters I see <code>function (param)</code> and then I see <code>function(param</code>. Is this just a matter of preference or is there a reason as to why there would be whitespace after the function or there would not be whitespace?</p>
