How does JS date comparison work?

Question

Let\'s assume I have a proper Date object constructed from the string: \"Tue Jan 12 21:33:28 +0000 2010\".

var dateString = \"Tue          


        

Answer 1

Date values in Javascript are numbers, as stated in the ECMA Script specification. So the Date values are compared as numbers.

This is a demo of your code (I set twitterDate in the future).

(function(){
    var dateString = "Tue Jan 12 21:33:28 +0000 2014";
    var twitterDate = new Date(dateString);

    var now = new Date();
    if (now < twitterDate) {
         document.write('twitterDate is in the future');
    }
    else
    {
        document.write('twitterDate is NOT in the future');
    }

})()​
