How to compare only date in moment js

Question

I am new to moment js  I have a date object and it has some time associated with it  I just want to check if that date is greater than or equal to today s date  excluding the time when comparing    var dateToCompare   2015-04-06T18 30 00 000Z   I just want to check if dateToCompare is equal or greater than today s date  I have checked isSame of moment js  but it seems to take string and only the date part  But I do not want to convert my date to string or manipulate it further  Because I am worried that javascript may do something unexpected when converting that date to string like adding the offset or dst etc   or may be I am wrong   Sample isSame   from docs  moment  2010-10-20   isSame  2010-10-20      Also I am looking for something like isSame   and isAfter   combined as one statement   I need to compare using moment js only Please do not suggest plain javascript date comparison

For checking one date is after another by using isAfter() method.

moment('2020-01-20').isAfter('2020-01-21'); // false
moment('2020-01-20').isAfter('2020-01-19'); // true

For checking one date is before another by using isBefore() method.

moment('2020-01-20').isBefore('2020-01-21'); // true
moment('2020-01-20').isBefore('2020-01-19'); // false

For checking one date is same as another by using isSame() method.

moment('2020-01-20').isSame('2020-01-21'); // false
moment('2020-01-20').isSame('2020-01-20'); // true

The docs are pretty clear that you pass in a second parameter to specify granularity      If you want to limit the granularity to a unit other than milliseconds  pass the units as the second parameter   moment  2010-10-20   isAfter  2010-01-01    year       false moment  2010-10-20   isAfter  2009-12-31    year       true       As the second parameter determines the precision  and not just a single value to check  using day will check for year  month and day    For your case you would pass  day  as the second parameter

You could use startOf  day   method to compare just the date  Example    var dateToCompare   moment  06 04 2015 18 30 00    var today   moment new Date      dateToCompare startOf  day   isSame today startOf  day
