How to compare starttime and endtime in javascript

Question

I would like to know how to compare two time in javascript, time is in 24 hours format.

function checkTime (stime,etime) {
  if(stime<etime){
   return true
  }
  else{
   return false
  }
}

var r1 = this.checkTime("10:20", "21:30"); // true
var r2 = this.checkTime("23:20", "19:30"); //false

Probably the best JS library out there to handle dates is [Moment.js](https://momentjs.com/) — yunzen, Aug 28 '20 at 06:52

Here simplest way:

function checkTime (stime,etime) {
            return Date.parse('01/01/1000 ' + stime) < Date.parse('01/01/1000 ' + etime)
        }

        var r1 = checkTime("10:20", "21:30"); // true
        var r2 = checkTime("23:20", "19:30"); //false

dd/mm/yy not important so just compare hh:mm
