There was a problem hiding this comment.
Switch is basically the react-router equivalent to a JavaScript switch statement.
Within the Switch component, Route and Redirect components are nested inside. Starting from the top Route/Redirect component in the Switch, to bottom Route/Redirect, each component is evaluated to be true or false based on whether or not the current URL in the browser matches the path/from prop on the Route/Redirect component.
if you do it without it wont have this true/false ability so you can render more than one route at a time and have to use the exact keyword to get around it :)

Don't know why and where to use Switch? :)
