[Mise] Update a count state value with the x-on event listener directive in Alpine JS

In this lesson, we define a "count" state value with the x-data directive provided by Alpine JS. This defines a new scoped component, which can have access to this state.

We then display the "count" value in our HTML with the x-text directive, which updates an element's innerText value.

We also hook up buttons with click event listeners with x-on:click, which allows us to modify the count value as desired.

<!-- Define the state for its children -->
<div x-data="{count: 0}">
  <button @click="count--">-1</button>
  <button @click="count++">+1</button>
  <!-- Show the state prop by using x-text -->
  <p>The current count is <strong x-text="count"></strong>.</p>
  <button @click="count = 0">reset</button>
</div>

You are not able to access the state outside the outmost div block
