For this challenge, you will need to create a writable computed ref :
<script setup lang="ts">
import { ref, computed } from "vue"
const count = ref(1)
const plusOne = computed(() => count.value + 1)
/**
* Make the `plusOne` writable.
* So that we can get the result `plusOne` to be 3, and `count` to be 2.
*/
plusOne.value++
</script>
<template>
<div>
<p>{{ count }}</p>
<p>{{ plusOne }}</p>
</div>
</template>
