momentjs

we want to check this condition currentyear < builtYear. It is string so its only comparing day, its not comparing month & year. so we want to convert its in Date Format.

then you can use only year by "YYYY" to parse date

Why is this question tagged C# and Oracle? If the immediate question is purely JavaScript then please remove those tags.

Here's how you can use moment to parse date string -

moment

var dateString = "29-06-2018 14:11";

console.log(moment(dateString, "DD-MM-YYYY HH:mm"));

var startDateString = "29-06-2018 14:11";
var endDateString = "30-06-2018 14:11";

var startDate = moment(startDateString, "DD-MM-YYYY HH:mm");
var endDate = moment(endDateString, "DD-MM-YYYY HH:mm");

console.log(startDate < endDate);

Try this:

var parts = '29-06-2018 14:11'.split(' ')[0].split('-');
// Please substract 1 from month part as javaScript counts months from 0:
// January - 0, February - 1, etc.
var mydate = new Date(parts[2], parts[1] - 1, parts[0]);
