why we use usehistory in react code example

Example 1: usehistory example

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

function Home() {
  const history = useHistory();
  return  history.push('/profile')}>Profile;
}

Example 2: useHistory react-router-dom

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

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