how to use useLocation in react code example

Example 1: react useLocation()

import React from "react";
import ReactDOM from "react-dom";
import {
  BrowserRouter as Router,
  Switch,
  useLocation
} from "react-router-dom";

function usePageViews() {
  let location = useLocation();
  React.useEffect(() => {
    ga.send(["pageview", location.pathname]);
  }, [location]);
}

function App() {
  usePageViews();
  return <Switch>...</Switch>;
}

ReactDOM.render(
  <Router>
    <App />
  </Router>,
  node
);

In react-router-dom version 6 
useHistory() is replaced by useNavigate() ;

import {useNavigate} from 'react-router-dom';
const navigate = useNavigate();
navigate('/home')

Example 3: usehistory

import { useHistory } from "react-router-dom";

function HomeButton() {
  let history = useHistory();

  function handleClick() {
    history.push("/home");
  }

  return (
    <button type="button" onClick={handleClick}>
      Go home
    </button>
  );
}
