const age = RandomDataGenerator.calculateAge('05-14-1995');
console.log(age); // Example: 30
7. dummyNumberGen()
Generates a random dummy phone number starting with the country code 91 (India).
const phoneNumber = RandomDataGenerator.dummyNumberGen();
console.log(phoneNumber); // Example: '919876543210'
8. dummyEmailGen()
Generates a random email using the first name and appends @xyz.com.
const email = RandomDataGenerator.dummyEmailGen();
console.log(email); // Example: 'rohan@xyz.com'
9. createUserObj(name, lastName, dob, age, email, phone_no)
Creates a user object with the provided details.
const user = RandomDataGenerator.createUserObj('Rohan', 'Sharma', '05-14-1995', 30, 'rohan@xyz.com', '919876543210');
console.log(user);
10. randomUserGen(length)
Generates an array of random user objects. You can specify the number of users to generate.
const users = RandomDataGenerator.randomUserGen(5);
console.log(users);
