Similar to watch with an extra option count which set up the number of times the callback function is triggered. After the count is reached, the watch will be stopped automatically.

import { watchAtMost } from '@vueuse/core'

watchAtMost(
  source,
  () => { console.log('trigger!') }, // triggered it at most 3 times
  {
    count: 3, // the number of times triggered
  },
)
