title: Storing array content in session storage
body: <p>I have data being displayed in a table. I delete a row, I need to hide it until that deletion is also exposed to the backend (It is exposed only after a minute).
  There is also auto-refresh that happens every 25 seconds, which brings the stale data (only after a minute, updated data is available to the backend).</p>
  
  <p>I decided to use sessionStorage to store the deleted objects and then whenever the stale data comes I compare and not show in the table.</p>
  
  <p>But sessionStorage doesn't support array. So when user deletes one object, goes to some other page, comes back and deletes another object (sessionStorage variable is overwritten) and then refreshes, only the last object deleted is hidden, all other deleted objects are shown</p>
  
  <p>I am not sure how to store the deleted objects in session storage.</p>
