::: tip
Pausable Watcher has been added to Vue , use instead.

Use as normal the watch, but return extra pause() and resume() functions to control.

import { nextTick, shallowRef } from 'vue'
const source = shallowRef('foo')
const { stop, pause, resume } = watchPausable(
source,
v => console.log(`Changed to ${v}!`),
)
source.value = 'bar'
await nextTick() // Changed to bar!
pause()
source.value = 'foobar'
await nextTick() // (nothing happend)
resume()
source.value = 'hello'
await nextTick() // Changed to hello!export interface WatchPausableReturn extends Pausable {
