Object Creation Methods

What creation pattern allows flexible object construction?

class UserBuilder {
  setName(name) {
    this.name = name;
    return this;
  }
  setAge(age) {
    this.age = age;
    return this;
  }
  build() {
    return new User(this);
  }
}

Factory Pattern
Singleton Pattern
Builder Pattern
This demonstrates the Builder pattern: 1) Separates object construction from representation, 2) Enables step-by-step object creation, 3) Provides fluent interface through method chaining, 4) Handles complex object construction, 5) Makes optional parameters clear, 6) Common pattern for objects with many configuration options.
