    <ul>
      <li v-for="user in users" :key="user.id">
        {{ user.name }} - Age: {{ user.age }}
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      users: [
        { id: 1, name: "Charlie", age: 30 },
        { id: 2, name: "Alice", age: 25 },
        { id: 3, name: "Bob", age: 28 }
      ]
    };
  },
  methods: {
    sortUsers() {
      this.users.sort((a, b) => a.name.localeCompare(b.name));
    }
  }
};
</script>
📝 Explanation

  • 🔹 List of users stored in data()

  • 🔹 Clicking "Sort by Name" sorts users alphabetically

  • 🔹 localeCompare() ensures case-insensitive sorting
