How to delete Web Storage?
Storing sensitive data on local machine could be dangerous and could leave a security hole. The Session Storage Data would be deleted by the browser immediately after the session gets terminated.
To clear a local storage setting you would need to call localStorage.remove('key'); where 'key' is the key to the value you want to remove. If you want to clear all settings, you need to call localStorage.clear() method.
<!DOCTYPE HTML>

<script>
localStorage.clear();
// Reset number of hits.
if( localStorage.hits ){
localStorage.hits = Number(localStorage.hits) +1;
