How to get the max date from an array of dates in TypeScript

Answer 1

function maxDate(dates : any) : Date {
    let max = dates[0],
    obj = new Date(dates[0]);
 
    dates.forEach(function(dt : Date) {
      if (new Date( dt ) > obj) {
        max = dt;
        obj = new Date(dt);
      }
    });
    return max;
}
 
const dates = ['2021/03/20', '2021/05/21', '2021/01/13', '2021/01/14', '2021/05/20']; 
           
console.log(maxDate(dates));
