function getRandomDate() {
  const startMillis = new Date('2020-06-02T00:00:00.000Z').getTime();
  const endMillis = new Date().getTime();
  const randomMillis = startMillis + Math.random() * (endMillis - startMillis);
  const randomDate = new Date(randomMillis);

  return randomDate;
}

for (var i = 0; i < 14000; i++) {
     data.push({ customerId: `CTM-${i % 10}`, worklistId: `WL-${i % 100}`, createdDateTime: getRandomDate() });
}
