title: How to create new component in @vue/composition-api in TS file?
body: <p>I have some components that I need to create in the TS file. Usually, I create by calling new Component because on our project we have <code>vue-component-decorator</code> but now I'm starting using <code>@vue/composition-api</code> and I can't call any component as new.</p>
  <p>Working:</p>
  <pre class="lang-js prettyprint-override"><code>// SomeComponent.vue
  import { Vue, Component } from 'vue-component-decorator';
  
  @Component
  export default SomeComponent extends Vue {}
  
  // Any .ts file
  const component = new SomeComponent();
  </code></pre>
  <p>Not working:</p>
  <pre class="lang-js prettyprint-override"><code>// SomeComponent.vue
  import { defineComponent } from '@vue/composition-api';
  
  export default defineComponent({});
  
  // Any .ts file
  const component = new SomeComponent();
  </code></pre>
