title: How to check if a user is logged in and how to save their information? (React)
body: <p>So pretty much I made a login page communicates with a backend to login a user. Now I want to take their data and store it for all my other components to know that there is </p>
  
  <ol>
  <li>A user logged in</li>
  <li>Have access to the user's information</li>
  </ol>
  
  <p>I figured based on past StackOverflow answers, that the best way to do this is using JWT and LocalStorage. But all the answer's I've encountered seem to use Redux. I'm not using Redux at all for my application, and have no clue how to use it, so I was wondering if there's a way to do it without redux.</p>
