Vue uses filters to format dates

<div id="app">
    <div>{{date }}</div>
    <div>{{date | format('yyyy-MM-dd')}}</div>
    <div>{{date | format('yyyy-MM-dd hh:mm:ss')}}</div>
    <div>{{date | format('yyyy-MM-dd hh:mm:ss:S')}}</div>
</div>

<script type="text/javascript" src="../js/vue.js"></script>
  <script type="text/javascript">
    // Vue.filter('format', function (value, arg) {
    // // console.log(arg);
    // if (arg == 'yyyy-MM-dd') {
    // var ret = '';
    // ret += value.getFullYear() + '-' + (value.getMonth() + 1) + '-' + value.getDate();
    // return ret;
    // }
    // })
    Vue.filter('format', function (value, arg) {
      function dateFormat(date, format) {
