Epoch to date conversion in javascript giving wrong answer

I am using Date to convert unix milliseconds epoch to a date.

So 1501783442 == Tuesday, 8 August 2017 12:35:57.

But javascript says its Sun Jan 18 1970 14:39:43 GMT+0530 (IST). 

<p id="demo"></p>

<script>
  var d = new Date(1501783442);
  document.getElementById("demo").innerHTML = d;
</script>

Jsfiddle link.

Whats going on here?

First of all, 1501783442 equals GMT: Thursday, August 3, 2017 6:04:02 PM according to https://www.epochconverter.com/.

Second of all, Unix uses seconds whereas Javascript uses milliseconds. So in order to convert, you must multiply by 1000, which then gives the correct result (corrected for the timezone that your browser lives in):

<p id="demo"></p>

<script>
  var d = new Date(1501783442 * 1000);
  document.getElementById("demo").innerHTML = d;
</script>
