Proxy Made With Reflect 4 Top < 99% REAL >

One of the most common use cases for a proxy is to enforce read/write rules.

function createSecureProxy(target, allowedRoles) 
  return new Proxy(target, 
    get(target, prop, receiver) 
      if (prop === 'adminSecret' && !allowedRoles.includes('admin')) 
        throw new Error('Access denied');
// Using Reflect for default behavior
      return Reflect.get(target, prop, receiver);
    ,
    set(target, prop, value, receiver) 
      if (prop === 'salary' && value > 100000 && !allowedRoles.includes('hr')) 
        throw new Error('Unauthorized to set high salary');
return Reflect.set(target, prop, value, receiver);
);
