</template>

<script>
import ComponentA from './ComponentA.vue';
import ComponentB from './ComponentB.vue';

export default {
  data() {
    return {
      currentComponent: 'ComponentA'
    };
  },
  methods: {
    toggleComponent() {
      if (this.currentComponent === 'ComponentA') {
        this.currentComponent = 'ComponentB';
      } else {
        this.currentComponent = 'ComponentA';
      }
    }
  },
  components: {
