JS logging

I've been doing a fair about of js development lately and console.log has been my friend. However, writing console.log() is a bit heavy. So instead I've been adding this to my files as  a quick way to log in javascipt.

function log() {
if (window.console && console.log)
console.log('{product or sitename} ::  ' + Array.prototype.join.call(arguments,' '));
}
