body: <p>Hey I am trying to comprehend what does express-async-handler do? </p>
  
  <p>It was used in one of the repo I was looking. </p>
  
  <p>From their docs, it says </p>
  
  <blockquote>
    <p>Simple middleware for handling exceptions inside of async express
    routes and passing them to your express error handlers.</p>
  </blockquote>
  
  <p>Link for the repo: <a href="https://www.npmjs.com/package/express-async-handler" rel="noreferrer">https://www.npmjs.com/package/express-async-handler</a></p>
  
  <p>Can someone please explain this with example? </p>
