const locales = {
  en: {
    author: "CRIMX",
    fruit: "apple",
    eat: "{{name}} eats {{fruit}}.",
  },
};

const i18n = new I18n("en", locales);

const MyComponent = () => {
  const t = useTranslate();

  return (
    <Trans message={t("eat")}>
      <strong data-t-slot="name">{t("author")}</strong>
      <i style={{ color: "red" }} data-t-slot="fruit">
        {t("fruit")}
      </i>
    </Trans>
