typescript -如何在特定位置扩展接口(扩展库xstate的基状态)

interface BaseState {
  // 定义基本的状态属性和方法
  state: string;
  transition(): void;
}

interface ExtendedState extends BaseState {
  // 定义扩展的状态属性和方法
  extendedState: string;
  extendedTransition(): void;
}

class MyClass implements ExtendedState {
  state: string;
  extendedState: string;

  constructor() {
    // 实现基状态和扩展状态的初始化
    this.state = "initial state";
    this.extendedState = "extended state";
  }

  transition() {
    // 实现基状态的转换逻辑
    console.log("Transitioning base state...");
  }

  extendedTransition() {
    // 实现扩展状态的转换逻辑
    console.log("Transitioning extended state...");
  }
}
