Factory class

Giovanny Gongora

Create an object without exposing the creation logic to the client and refer to newly created objects using a common interface.

export interface Product {
  method(param?: any) : void;
}
export class ConcreteProductA implements Product {
  method = (param?: any) => {
    return "Method of ConcreteProductA";
  }
}
export class ProductFactory {
  public static createProduct(type: string) : Product {
    if (type === "A") {
      return new ConcreteProductA();
    }
    return null;
  }
}
