      <b>{{ count }}</b>
    </template>
  </i18n-t>
</template>

<script>
import { useI18n } from 'vue-i18n'

export default {
  setup() {
    const { t } = useI18n({
      locale: 'en',
      messages: {
        en: {
          message: {
            plural: 'no bananas | {n} banana | {n} bananas'
          }
        }
      }
    })
    const count = ref(0)

    return { count, t }
  }
}
</script>
