JSON Object, undefined?

I'm trying to develop a web application using jQuery, AJAX and JSON.
I have this code:

console.log(response.s);

if (response.s == true) {

    alert('good');

} else {

    alert('bad');

}

This response (via console.log() on Firebug) seems to be:

{s:true}

Which seems to be a JSON object right?
Well, the line console.log(response.s); on the first code I added here returns undefined. What's the problem?

What is typeof (response)? if it's a string then you have to parse it, first. (You'd be accessing the s field of a string, which doesn't exist, so JavaScript gives you undefined instead of throwing an Exception or whatever.)
