Object Creation Methods

What pattern ensures object immutability?

const createImmutable = (obj) => {
  const copy = JSON.parse(JSON.stringify(obj));
  return new Proxy(copy, {
    set: () => false,
    deleteProperty: () => false,
    defineProperty: () => false
  });
};

Decorator Pattern
Proxy Pattern
This implements the Proxy pattern for immutability: 1) Intercepts object operations, 2) Prevents modifications to target object, 3) Creates defensive copies, 4) Maintains object integrity, 5) Throws errors on modification attempts, 6) Common pattern for implementing immutable data structures.
Facade Pattern
Adapter Pattern
