const handler = has(obj, prop) if (prop.startsWith("_")) return false; // pretend property doesn't exist
let handler = get(target, prop, receiver) // receiver ensures 'this' refers to the Proxy, preserving prototype chain lookups return Reflect.get(target, prop, receiver);
return Reflect.set(target, prop, value, receiver); , deleteProperty(target, prop) if (!hasPermission("delete", prop)) throw new Error( Access denied: cannot delete "$prop" );
The synthesis of these concepts leads to the (or Forwarding Proxy). This is a standard design pattern where the proxy traps simply delegate to the corresponding Reflect method.
