can javascript compare dates code example

Example 1: compare dates in js

var date1 = new Date('December 25, 2017 01:30:00');
var date2 = new Date('June 18, 2016 02:30:00');

//best to use .getTime() to compare dates
if(date1.getTime() === date2.getTime()){
    //same date
}

if(date1.getTime() > date2.getTime()){
    //date 1 is newer
}

Example 2: date compare in js

var x = new Date('2013-05-23');
var y = new Date('2013-05-23');

// less than, greater than is fine:
x < y; => false
x > y; => false
x === y; => false, oops!

// anything involving '=' should use the '+' prefix
// it will then compare the dates' millisecond values
+x <= +y;  => true
+x >= +y;  => true
+x === +y; => true
