I want to know if a date (2021-11-09) is after another date (2021-11-11) in YYYY-MM-DD format, which should be false, right ?
console.log(
moment("2021-11-09", "YYYY-MM-DD", true).isAfter(
"2011-11-11",
"YYYY-MM-DD",
true
)
);
but, above code return true.
the doc of momentjs states:
If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.
As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day
So you should use a unit instead of format string though it seems the result is same.
console.log(
moment("2021-11-09", "YYYY-MM-DD", true).isAfter(
"2011-11-11",
"day" //"YYYY-MM-DD"
)
)
console.log(
moment("2021-11-09", "YYYY-MM-DD", true).isAfter(
"2021-11-11",
"day" //"YYYY-MM-DD"
)
)<script src="https://unpkg.com/moment@2.29.1/moment.js"></script>The dates you're comparing in code and the ones in your questions are not aligned. And code is returning true correctly. Because 2021-11-09 is indeed after 2011-11-11
