how to get data from localstorage in javascript

//localStorage is an object, so values are stored by key name
//data from localStorage is always stored in strings
//usually the values at each key are stringified objects in JSON format, therefore we must parse them
var data = JSON.parse(localStorage.getItem("key name"));//make sure the "key name" exists in the localStorage

set localstorage value

localStorage.setItem("mytime", Date.now());
