Use URL Parameters with React Router v4

Unfortunately, it's not clear how to access match when referencing a component in the Route element. How does one get a reference to match in the more typical case like the one below?

<Route path="/somplace/:someParam" component={ SomeComponent } /> 

assuming SomeComponent is defined something like:

class SomeComponent extends Component {
   render() {
         // ... how to get the value of someParam here??
   }
}

...turns out its on props

class SomeComponent extends Component {
    render() {
        return (<h1>{ this.props.match.params.someParam }</h1>);
    }
}

Github project isn't working on both codesandbox as well as on local, getting below error:

Failed to compile.

Would suggest, If we can directly have codesandbox embedded in to the lessons itself, rather providing Github URL.
