How to implement substring replacement in string with jsx support?

Question

JavaScript

How to implement similar behavior with jsx support?

const array = ['Тверь', 'тверская', 'Тве', 'Колыма'];
const search = 'тве';
const r = () => {
  const rg = new RegExp(search, 'gi');
  return array.map(item => item.replace(rg, "<b>$&</b>"));
}

That is, each element must not be a string in order to be able to embed it in the DOM.
