Question 11
Consider the following html.
<div id="app"> <p>{{ message }}</p> <button @click="updateMessage">Click me</button></div>
<script>new Vue({ el: '#app', data: { message: 'Hello!' }, methods: { updateMessage() { this.message += '!'; } }});</script>Assuming vue cdn has been added to the html and the html format is correct. What would be the output on the screen after clicking the button twice?
