const dateRegex = /^\d{4}-\d{2}-\d{2}$/;
const dateString = "2022-01-01";
if (dateRegex.test(dateString)) {
  console.log("Valid date string");
} else {
  console.log("Invalid date string");
}

const dateRegex = /^\d{4}-\d{2}-\d{2}$/;
const dateString = "2022-01-01";
if (dateRegex.test(dateString)) {
  const date = new Date(dateString);
  if (isNaN(date.getTime())) {
    console.log("Invalid date");
  } else {
    console.log("Valid date");
  }
} else {
  console.log("Invalid date string");
}
