how to pass a string as a parameter in react

Question

I am trying to pass a string from redux to a parameter, I am not sure about the syntax, "lang" is a string 100%

const About = () => {
  const lang = useSelector((state) => state.counter.lang);

  const about = {
    ru: {
      aboutTitle: "rus",
    },
    tr: {
      aboutTitle: "tr",
    },
    en: {
      aboutTitle: "en",
    },
  };

  return (
         <h2>{about.lang.aboutTitle}</h2>
  );
};
