使用 { immediate: true } 监听值的简写形式。

使用方法

类似于 watch，但使用 { immediate: true }

import { watchImmediate } from '@vueuse/core'

const obj = ref('vue-use')

// 从某些外部存储/组合中更改值
obj.value = 'VueUse'

watchImmediate(obj, (updated) => {
  console.log(updated) // 控制台日志将被记录两次
})

  T extends Readonly<WatchSource<unknown>[]>,
