title: Typescript how to add new item to empty array of objects
body: <p>I have component in vue 2 which is written in typescript:</p>
  
  <pre><code> data: {
      userfilterresults: []
    },
    mounted() {
      axios.get("/Tasks/GetTasks")
        .then(response =&gt; {
          this.userfilterresults = response.data;
        });
    },
    methods: {
      addtab() {
        // this push bellow is the reason of the error:
        this.userfilterresults.push({
          id : '-1',
          userid : '1',
          name : 'newtab'
        });
  </code></pre>
  
  <p>And I want to add new item to existed array userfilterresults but I've got error: Argument type {..} is not assignable to parameter of type never
  How I can add new item to the array?</p>
