12 digit Aadhaar Card Number validation in JavaScript

Yes, it is possible to validate an Aadhaar card number using JavaScript. Here’s an example function that checks whether an Aadhaar number is valid or not:

function validateAadhaar(aadhaar) {
  // The Aadhaar number must be 12 digits long
  if (aadhaar.length !== 12) {
    return false;
  }

  // The first digit must be between 1 and 9
  if (aadhaar.charAt(0) < '1' || aadhaar.charAt(0) > '9') {
    return false;
  }

  // The last digit must be a valid checksum
  var checkSum = 0;
  for (var i = 0; i < 11; i++) {
    var digit = parseInt(aadhaar.charAt(i));
    checkSum += (digit * (11 - i));
  }
  var lastDigit = (checkSum % 11);
  if (lastDigit !== 0 && lastDigit !== 1) {
    lastDigit = 11 - lastDigit;
  }
  return (lastDigit === parseInt(aadhaar.charAt(11)));
}

To use this function, you can pass an Aadhaar number as a string to the validateAadhaar function. The function will return true if the Aadhaar number is valid and false otherwise.

Here's an example usage:

var aadhaar = "123456789012";
if (validateAadhaar(aadhaar)) {
  console.log("Valid Aadhaar number");
} else {
  console.log("Invalid Aadhaar number");
}

Note: This function only checks the format of the Aadhaar number and its checksum, it does not verify whether the Aadhaar number is actually assigned to a particular individual or whether it is being used fraudulently.
