javascript date comparison not working, even in console

Question

I am having an issue with a javascript date comparison. I can output the objects in the console and everything looks right, but they always evaluate to false.

var date1 = new Date('2013','01','01'); 
var date2 = new Date('2015','01','01'); 
console.log("date1=" + date1);
console.log("date2=" + date2);
console.log("date1 > date2" + date1 > date2);
console.log("date1 < date2" + date1 < date2);

>>date1=Fri Feb 01 2013 00:00:00 GMT-0500 (EST)
>>date2=Sun Feb 01 2015 00:00:00 GMT-0500 (EST)
>>false
>>false

`"date1 > date2" + date1 > date2` --- what does this mean? You append a `date1` to a string, then compare the compound string and another date? It makes no sense. — zerkms, Jul 13 '15 at 00:39
in the `console.log` context, the `+` is concatenating. Use comma instead of plus. — CrayonViolent, Jul 13 '15 at 00:41

This is a matter of operator precedence:

Operator precedence determines the order in which operators are evaluated. Operators with higher precedence are evaluated first.

This makes a string with "date1 > date2" and date1 and compares it with date2:

"date1 > date2" + date1 > date2

This makes a string with "date1 > date2" and the comparison of date1 > date2:

"date1 > date2" + (date1 > date2)

Also you shouldn't compare date objects directly.
