Here is a little piece of code you can use in your project for slightly smarter console messages. Objects and arrays are handled differently when logged to the console than strings. Firebug gives you a stringified version of the object while console.dir gives you an expandable object. Both give you the expandable object in Chrome. To work around this you can use this little snippet, it will always give you the correct version.
var debug = function(message) {
"object" === typeof console && ("object" === typeof message || "array" === typeof message ? console.dir(message) : console.info(message));
};
