使用自动命名时状态机不一致

class StateMachine {
  constructor() {
    this.currentState = null;
    this.states = {};
  }

  addState(name, state) {
    this.states[name] = state;
  }

  setInitialState(name) {
    this.currentState = this.states[name];
  }

  transition(eventName) {
    const nextState = this.currentState[eventName];
    if (nextState) {
      this.currentState = this.states[nextState];
    } else {
      console.error(`Invalid event: ${eventName}`);
    }
  }
}

// 定义状态
const stateA = {
  event1: 'stateB',
  event2: 'stateC'
};

const stateB = {
  event3: 'stateA'
};

const stateC = {
  event4: 'stateA'
};

// 创建状态机
const fsm = new StateMachine();
fsm.addState('stateA', stateA);
fsm.addState('stateB', stateB);
fsm.addState('stateC', stateC);

// 设置初始状态
fsm.setInitialState('stateA');

// 触发事件
fsm.transition('event1'); // 转换到 stateB
fsm.transition('event3'); // 转换到 stateA
