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

I think yes. Using if (now < twitterDate), it evaluates to if (now.valueOf(). valueOf() delivers the number of milliseconds passed since 01/01/1970 00:00:00, so the comparison of those 2 numbers is valid.

check it like this

var then = new Date("Tue Jan 12 21:33:28 +0000 2010")
   ,now  = new Date;

console.log(then.valueOf(),'::',now.valueOf(),'::',now 1263332008000 :: 1352365105901 :: false
