// Assume 'phoneNumber' is the quantity you are checking.
// Assume 'whitelist' and 'blacklist' are arrays (or related information buildings).

perform isNumberAllowed(phoneNumber, whitelist, blacklist) 
  if (whitelist.consists of(phoneNumber)) 
    return true; // Quantity is on the whitelist, permit it.
  
  if (blacklist.consists of(phoneNumber)) 
    return false; // Quantity is on the blacklist, block it.
  
  return true; // Not on both record, deal with as allowed (or apply default blocking guidelines).


// Instance utilization:
const myNumber = "555-123-4567";
const myWhitelist = ["555-111-2222", "555-123-4567"];
const myBlacklist = ["555-999-8888", "555-777-6666"];

if (isNumberAllowed(myNumber, myWhitelist, myBlacklist)) 
  console.log(myNumber + " is allowed to name/textual content.");
 else 
  console.log(myNumber + " is blocked.");

 

“`

This code is a simplified instance. In a real-world software, the lists would doubtless be saved extra persistently (e.g., in a database) and the logic may be extra advanced to deal with wildcards and different blocking guidelines. Nonetheless, the basic precept stays the identical: checking if a quantity exists on both the whitelist or the blacklist earlier than permitting or blocking communication.

The `isNumberAllowed` perform is the core of the method. It first checks if the quantity is on the whitelist. Whether it is, the perform instantly returns `true`, indicating the quantity is allowed. If not, it checks the blacklist. If the quantity is on the blacklist, the perform returns `false`, indicating it needs to be blocked.

If the quantity is on neither record, the perform returns `true`, or it might apply default guidelines, equivalent to permitting the decision/textual content or making use of a extra advanced blocking technique. This enables for a versatile system that prioritizes each allowed and blocked numbers.
