ES6 Classes & Constructors

What design pattern does the clone method implement?

class User {
  constructor(id, name) {
    Object.assign(this, {id, name});
  }
  
  clone() {
    return Object.assign(Object.create(Object.getPrototypeOf(this)), this);
  }
}

Factory pattern
Singleton pattern
Prototype pattern
The clone method implements the Prototype pattern: 1) Creates a new object with the same prototype as the original, 2) Copies all properties from the original to the new object, 3) Enables object creation by copying existing objects rather than instantiating classes, 4) Useful when object creation is expensive, 5) Maintains the prototype chain for proper inheritance, 6) Provides a way to create objects without knowing their specific class.
Builder pattern
