It also includes a function to validate and potentially modify the postcode. There is no indication of malicious behavior such as data exfiltration, keylogging, or unauthorized access. The risk score is low, but it is always advisable to review the entire context of the code and the surrounding application for a comprehensive security assessment."

  "riskscore": 1,
  "reasons": "The provided JavaScript code appears to be handling form validation by checking if certain fields are filled and displaying or hiding error messages accordingly. There is no indication of malicious activity such as data exfiltration, unauthorized access, or harmful operations. The code is primarily focused on user input validation and error handling, which is common in web forms. However, the use of the 'checkPostCode' function without seeing its implementation leaves a small uncertainty, hence a minimal risk score."
