localStorage.removeItem() Method Example

First, we add a key and value pair to localstorage.

localStorage.setItem("firstName", "Ramesh");
Where "firstName" is the key and "Ramesh" is the value. Also, note that localStorage can only store strings.
To store arrays or objects you would have to convert them to strings.
To do this we use the JSON.stringify() method before passing to setItem() .
var user = {
 firstName : "Ramesh",
 lastName : "Fadatare"
localStorage.setItem("id", JSON.stringify(user));
