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;
