function isValidDate(dateString) {
  // Create a Date object using the input date string
  const date = new Date(dateString);

  // If the Date object is invalid or the input is not a valid date string, return false
  if (isNaN(date) || date.toString() === 'Invalid Date') {
    return false;
  }

  // Check if the day, month, and year extracted from the Date object match the input
  const [year, month, day] = [date.getFullYear(), date.getMonth() + 1, date.getDate()];
  const [inputYear, inputMonth, inputDay] = dateString.split('-').map(Number);

  if (year !== inputYear || month !== inputMonth || day !== inputDay) {
    return false;
  }

  // Return true if the input date is valid
  return true;
}

// Usage example
const date1 = '2022-01-31';
console.log(isValidDate(date1)); // true

const date2 = '2022-02-30';
console.log(isValidDate(date2)); // false
