Learn Factory, Singleton, and Builder patterns. Creational patterns handle object creation elegantly, decoupling construction from usage.

• Factory
• Singleton
• Builder patterns

class ButtonFactory {
  static createButton(type) {
    switch (type) {
      case 'primary': return new PrimaryButton();
      case 'secondary': return new SecondaryButton();
      default: throw new Error('Unknown button type');
// ...

• Factory pattern works
• Singleton works

• Factory: return appropriate object type based on parameter
• Singleton: control instantiation, ensure only one instance
• Builder: construct complex objects step-by-step
