My struggle to learn React(bradfrost.com)

  const path = findThePath();

  class Router extends Component {
    render() {
      if (path === "/about") return <About />
      else if (path.match(someRegex)) {
        const data = parseSomePath(path);

        return <Page { ...data } />
      } else {
        return <Default />
      }
    }
  }

    m('.foo', {...attrs}, ...children)

    import React from "react";
    import { connect } from "react-redux";

    function _HelloWorld({name}) {
      return <div className="intro">{name}</div>
    }

    function mapState(state, ownProps) {
      return {
        name: state.name
      }
    }
   
    function mapDispatch(dispatch, ownProps) {
      return {}
    }

    export const HelloWorld = connect(mapState, mapDispatch)(_HelloWorld)
