Design Pattern

常用设计模式

创建型

单例

class Singleton {
  static _instance: Singleton;
  private constructor() { }
  public static get instance(): Singleton {
    if(Singleton._instance) {
      Singleton._instance = new Singleton();
    }
    return Singleton._instance;
  }
}

原型

interface IGame<T> {
  clone(): T;
}
class Game implements IGame<Game> {
  constructor(private name: string) {}

  clone(): Game {
    return new Game(this.name)
  }
}
