<script setup lang="ts">
import { shallowRef, watch } from "vue"

const state = shallowRef({ count: 1 })

// 回调没被触发
watch(state, () => {
  console.log("State.count Updated")
}, { deep: true })

/**
 * 修改以下代码使watch回调被触发
 *
*/
// 方法1
state.value = {count: 2};
// 方法 2
state.value.count = 2;
triggerRef(state);

      {{ state.count }}
