Working Without proto

Modern JavaScript provides clean methods for prototype management:

Method	What It Does
Object.create(proto)	Creates a new empty object with proto as its [[Prototype]]
Object.getPrototypeOf(obj)	Returns the [[Prototype]] of obj
Object.setPrototypeOf(obj, proto)	Changes the [[Prototype]] of an existing object

let animal = { eats: true };
let rabbit = Object.create(animal);
rabbit.name = 'White Rabbit';

console.log(rabbit.eats); // true — inherited
console.log(Object.getPrototypeOf(rabbit) === animal); // true

The " Pure Dictionary " Pattern

// No inherited properties — safe for arbitrary keys
const safeMap = Object.create(null);
safeMap['toString'] = 'my value'; // No conflict with Object.prototype!
