each element contains the same value. When checked against this value by themselves, everything checks out. But when compared against eachother, they are not shown as being equal. help! thanks!
time[x] == "2013-02-26 14:00:00" ?
true
reference[x] == "2013-02-26 14:00:00" ?
true
time[x] == reference[x] ?
false
time[x].valueOf() == reference[x].valueOf() ?
false
This might happen because the two variables are of different types.
In case one of the variables holds a Date instance and the other a String, comparing both of them to a string literal will return true, while comparing their valueOf() results will return false, since valueOf() of a Date returns number of milliseconds since epoch, not the human-readable representation of a date (as opposed to toString()).
var a = new Date()
a.toString() //"Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)"
a.valueOf() //1361918511306
var b = "Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)"
b.toString() //"Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)"
b.valueOf() //"Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)"
a == "Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)" //true
b == "Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)" //true
a == b //true
a === b //false - types are being compared as well
a.valueOf() == b.valueOf() //false - 1361918511306 compared to "Wed Feb 27 2013 01:41:51 GMT+0300 (MSK)"
time[x].toString() == reference[x].toString()?new String("2013-02-26 14:00:00");
