Vue 3.0 配合 typescript 使用 watch 侦听多个源时类型是否有错误?

当我写如下代码时:

import { watch, ref, reactive } from 'vue'

const count = ref<string>('')
const reactiveCount = reactive({
    count: 0
})

watch([count, () => reactiveCount.count], ([newCount, newRefCount]) => {
    // ...
})

观察发现 newCountnewRefCount 的类型均是 string | number

那这样的话只能用 typeof 之后再去使用侦听来的值了吗...
