具有額外 EventFilter 控制的 watch。

用法

與 watch 類似，但提供額外的選項 eventFilter，將應用於回呼函式。

import { debounceFilter, watchWithFilter } from '@vueuse/core'

watchWithFilter(
  source,
  () => { console.log('changed!') }, // callback will be called in 500ms debounced manner
  {
    eventFilter: debounceFilter(500), // throttledFilter, pausableFilter or custom filters
  },
)
