how to get code suggestions for react components

    import React, { Component } from 'react';
    import PropTypes from 'prop-types';
    import UiStore from './store';

    /**
     * @typedef Props
     * @prop {UiStore} uiStore
     */

    /**
     * @extends {Component<Props, {}>}}
     */
    export default class DeviceMirror extends Component {
        static propTypes = {
            // not needed for intellisense but prop validation does not hurt
            uiStore: PropTypes.instanceOf(UiStore),
        }
        /**
         * @param {Props} props - needed only when you don't write this.props....
         */
        constructor(props) {
            super(props);
            this.s = props.uiStore.str;
        }
        render() {
            const { uiStore } = this.props;
            return <p>{uiStore.str}</p>;
        }
    }
