console.log(beginningTime.isSame(endTime)); //expect true<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js"></script>I am using moment js to get if 2 date are the same using the above pattern. But now i get false instead of true. How to solve the issue?
Instead of formatting the beginningTime and endTime separately, you should take a look at the 'granularity' argument for isSame().
I made a few adjustments to your code for it to work, and also look cleaner.
var beginningTime = moment(1635750314812); // Today date (from timestamp)
var endTime = moment() // Today date
console.log(beginningTime.isSame(endTime, 'day')); //expect true<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js"></script>It first simply creates a moment of your timestamp and a moment of right now, whenever now is.
Then it will compare the two moments with a granularity of a day, effectively checking if the day and everything bigger (month, year) is the same.
