You can not useRegex should be less than the current date

function formatAndLessThanCurrentDate(varDate)
{

  let today = new Date();
  today.setHours(0,0,0,0);
  let dateReg = /[0-9]{2}[\/]{1}[0-9]{2}[\/]{1}[0-9]{4}$/
  let matches =dateReg.test(varDate);
  if(matches){
    if(new Date(varDate) < today) {
      alert("Working!");
    }
    else
    {
       alert("not less than CurrentDate!");
    }
  }
  else{
    alert("not matches!");

  }
 }

formatAndLessThanCurrentDate("10/12/2021");
