Factory Functions & Singleton Pattern

What pattern is demonstrated by the withLogging function?

const withLogging = (target) => {
  return {
    ...target,
    log(message) {
      console.log(`Log: ${message}`);
    }
  };
};

function createPerson(name) {
  const person = {
    name,
    greet() {
      return `Hello, I'm ${this.name}`;
    }
  };
  
  return withLogging(person);
}

Factory pattern
Decorator pattern
The withLogging function demonstrates the decorator pattern: 1) It takes an existing object and enhances it with new capabilities, 2) It doesn't modify the original object's structure but wraps it with new functionality, 3) It uses composition rather than inheritance to extend behavior, 4) Multiple decorators can be applied in sequence for layered functionality, 5) It follows the open/closed principle by extending objects without modifying their original implementation, 6) This pattern is useful for dynamically adding features to objects.
Observer pattern
Singleton pattern
