title: How to set localstorage item back to null.
body: <p>I'm using a system to alert users when a major update has happened to a site, and I do it with LocalStorage, when I made the system, I made the system check if tip was "null", then set "tip" to true when they got the alert. Now, I would like to set the 'tip' localstorage back to null, and use "tip2" instead. </p>
  
  <p>Would I do this? localStorage.setItem('tip', 'null');</p>
