effectScope API medium #Composition API #Reactivity:Advanced

By webfansplz @webfansplz

Take the Challenge    简体中文

For this challenge, you'll use Reactivity API: effectScope to complete the challenge. Here's what you need to implement 👇:

<script setup lang="ts">
import { ref, computed, watch, watchEffect } from "vue"

const counter = ref(1)
const doubled = computed(() => counter.value * 2)

// use the `effectScope` API to make these effects stop together after being triggered once

watch(doubled, () => console.log(doubled.value))
watchEffect(() => console.log("Count: ", doubled.value))

counter.value = 2

setTimeout(() => {
  counter.value = 4
})

</script>

<template>
  <div>
    <p>
      {{ doubled }}
    </p>
  </div>
</template>
