    </div>
    <script src="../js/vue.js"></script>
    <script type="text/javascript">
      Vue.filter('toFixed', function (price, limit){
          return price.toFixed(limit)
      })
      Vue.filter('toUSD',function (tofixed){     
        return "$"+tofixed
      })
      const app = new Vue({
          el: '#app',     
          data:{
              price:435.333,
              strval:"htzd1234"
          },
          filters: {
            suffix(text, length, suffixchar = '...') {
              return text.substring(0, length) + suffixchar;
            }
          },

      })
    </script>
  </body>
