+The Coupon Code.js

/*Description:

Your online store likes to give out coupons for special occasions. Some customers try to cheat the system by entering invalid codes or using expired coupons.

Your mission: 
Write a function called checkCoupon to verify that a coupon is valid and not expired. If the coupon is good, return true. Otherwise, return false.

A coupon expires at the END of the expiration date. All dates will be passed in as strings in this format: "June 15, 2014"
*/
function checkCoupon(enteredCode, correctCode, currentDate, expirationDate){
  var convertCurrent = new Date(currentDate);
  var convertExpire = new Date(expirationDate);  
  
  if ((enteredCode === correctCode) && (convertCurrent <= convertExpire)) {
    return true;
  }
  return false;
}
