new Vue({
  el: '#app',
  data: {
    sampleData: [/* your sample data */],
    duplicateValues: []
  },
  methods: {
    checkDuplicateValues: function() {
      // logic to check duplicate values in sampleData
      // and store them in duplicateValues array
    }
  },

    this.checkDuplicateValues(); // call the method when the Vue instance is mounted
  }
});
