Reflect.get and Reflect.set are used to interact with both the internal cache and the target object consistently. Reflect.ownKeys ensures that enumeration ( for...in , Object.keys ) sees both pre-loaded and lazy-loaded properties correctly.
return Reflect.set(target, prop, value, receiver); , deleteProperty(target, prop) console.warn(`DELETE $String(prop) attempted`); return false; // Disallow deletion for safety proxy made with reflect 4 top
set: function(target, prop, value) return Reflect.set(target, prop, value); // Automatically returns boolean success status Reflect
return undefined; );
