Mustache(day4)

Mustache語法：{{}}

 <div id="app">
  <h2>
    {{firstName+lastName}}
  </h2>
  <h2>
    {{counter*2}}
  </h2>
  </div>
  <script src="js/vue.js">
  </script>
  <script>
    const app = new Vue({
      el: '#app',
      data: {
        firstName: 'st',
        lastName: 'sy',
        counter:100
      }
    })
  </script>

Mustache中不僅可以插入變量，還可以插入表達式。
