In my .vue file, I have the following code snippet:
<template>
<button @click="entries.push(3)">
Press me!
</button>
<ul>
<li v-for="entry in entries" :key="entry">
{{ entry }}
</li>
</ul>
</template>
<script setup>
const entries = [1, 2]
</script>
When I click the button, I expect a third li element to be added but nothing happens. What could be causing this issue?
I created a playground with the solution implemented: https://codesandbox.io/s/beautiful-pond-8jg5zw?file=/src/App.vuee
<template>
<button @click="entries.push(3)">Click me!</button>
<ul>
<li v-for="entry in entries" :key="entry">
{{ entry }}
</li>
</ul>
</template>
<script setup>
import { ref } from "vue";
const entries = ref([1, 2]);
</script>
<style>
