withHistory is mutable code example

Example 1: use history in react router

import {createBrowserHistory} from 'history';import {useRouterHistory, Router, Route} from 'react-router';const history = useRouterHistory(createBrowserHistory)({  basename: '/basename'});history.listen(location => {  history.push('/super/url');});const router = (            …      );

  }
