Object Creation Methods

What inheritance pattern is demonstrated?

class Component {
  constructor() {
    if (this.constructor === Component) {
      throw new Error('Abstract class');
    }
  }
  
  operation() {
    throw new Error('Abstract method');
  }
}

class ConcreteComponent extends Component {
  operation() {
    return 'ConcreteComponent';
  }
}

Multiple Inheritance
Template Method Pattern
Abstract Class Pattern
This demonstrates the Abstract Class pattern: 1) Defines template for derived classes, 2) Forces implementation of abstract methods, 3) Prevents instantiation of base class, 4) Ensures contract adherence, 5) Provides common interface, 6) Common pattern in hierarchical class structures.
