Exercise:

Use the shorthand of a Vue directive so that the light bulb turns on and off when the button is clicked.

<div id="app">
  <div id="lightDiv">
    <div v-show="lightOn"></div>
    <img src="img_lightBulb.svg">
  </div>
  <button 
w3exercise_input_no_0
=" lightOn =! lightOn ">Switch light</button>
</div>

<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
<script>
  const app = Vue.createApp({
    data() {
      return {
        lightOn: false
      }
    }
  })
  app.mount('#app')
</script>
