javascript - React opening a new page on link click -

how can open/direct page on link click using reactjs.

from index.html want provide link open new page. have added following code

import react 'react'; class header extends react.component {   render() {     return               <div>                  <a href="#/trialuser"> trial user</a>             </div>   } export default header;
