Comparing two dates in jquery script

Question

I'm trying to compare two same dates in the browser console and getting the result as false. I don't understand how is it comparing as both the dates are the same?

$(function()
{
  var d1 = new Date("01-12-2001");
  var d2 = new Date("01-12-2001");
  
  console.log(d1 == d2);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

but here if try to compare with GT and LT then its working.

Answer 1

It is checking for object equality. Compare the time instead.

$(function()
{
  var d1 = new Date("2001-12-01");
  var d2 = new Date("2001-12-01");
  
  console.log(d1.getTime() == d2.getTime());
});
