Validate SSN

Write a JavaScript function to check whether a given value is a social security number or not.

Sample Solution:

JavaScript Code:

function is_socialSecurity_Number(str)
{
 regexp = /^(?!000|666)[0-8][0-9]{2}-(?!00)[0-9]{2}-(?!0000)[0-9]{4}$/;
  
        if (regexp.test(str))
          {
            return true;
          }
        else
          {
            return false;
          }
}

console.log(is_socialSecurity_Number("019-90-5680"));

console.log(is_socialSecurity_Number("K8V-3Y1"));
