Wonder how this works?
Storage is the Prototype of both localStorage and sessionStorage.
Got it?
localStorage.set('myKey',{a:[1,2,5], b: 'ok'}); //can set a json Object
localStorage.assign('myKey',{a:[6], c:42}); //shallow merge using Object.assign
localStorage.has('myKey'); // --> true
localStorage.get('myKey'); // --> {a:[6], b: 'ok', c:42}
localStorage.keys(); // --> ['myKey']
localStorage.remove('myKey'); // -
native:
localStorage.clear();
localStorage.length;
