title: Create data array with loop in vue
body: <p>I have this data array holding repetitive item in the component:</p>
  
  <pre><code>data () {
  datasets: [ {
          text: "",
          value:[ {
            x: "",
            y: "",
            type: 'bar'
          }]
          },
            {
          text: "",
          value: [{
            x: "",
            y: "",
            type: 'bar'
          }]
          },
          {
          text: "",
          value: [{
            x: "",
            y: "",
            type: 'bar'
          }]
          }
  ]
  }
  </code></pre>
  
  <p>As you can see those are the same items. Is it possible to set this data like</p>
  
  <pre><code>datasets:[ {
          text: "",
          value:[ {
            x: "",
            y: "",
            type: 'bar'
          }]
          } * 3 ]
  </code></pre>
  
  <p>Instead of hardcoding it several times?</p>
