typescript + react 中的 class 组件如何让 props 合法

interface Props{
    word: string;
}
export default class TamWordTitle extends React.Component<Props, {}> {
    public static defaultProps = { word: '' };
    public render(): JSX.Element {
      const { word } = this.props;
      return (
        <div className="tam-word-title">
            <div className="level-line"></div>
            <div className="ver-line"></div>
            <div className="word">{word}</div>
            <div className="ver-line"></div>
            <div className="level-line"></div>
        </div>
      );
    }
}
