    el:'.card-body',
    data:{
      items:[
           { message: 'python' },
           { message: 'C'},

          // delete last

  </div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.18/vue.min.js"></script>
<script>
  Vue.config.devtools = true
  var app = new Vue({
    el:'.card-body',
    data:{
      items:[
           { message: 'python' },
           { message: 'C'},
           { message: 'C#'},
           { message: 'Perl'},
           { message: 'MySQL'},

    },
      methods: {

        this.items.splice(this.items.indexOf(item), 1);
        //remove one element starting from the element 'item'
