Question

What’s the best (clearest, shortest, fastest, etc.) way to determine whether a Date object is equal to, say, July 4, 2012?

For example, this works but is rather verbose:

if (date.getFullYear() === 2012 && date.getMonth() + 1 === 7 && date.getDate() === 4)

Is there a more elegant solution?

(In my actual scenario, server-side code will be plugging in the specific date to test against. Also, the date comes from a jQuery UI datepicker and so will have a time component of 00:00:00.)

Answer 1

Construct a new date and compare the results of getTime:

var existingDate = new Date('2012', '6', '4');
new Date('2012', '6', '4').getTime() == existingDate.getTime();
