我正在尝试在React组件中创建一个时钟计时器.但是我遇到了困难.任何帮助,将不胜感激.

import React from "react";
import ReactDOM from "react-dom";

export default class App extends React.Component {
  render() {
    return (
      <ShowDate />
    );
  }
}

ReactDOM.render(<App/>, document.getElementById('app'));

function ShowDate() {
  return {new Date().toLocaleTimeString()};
}

setInterval(ShowDate, 1000);
