Chaining a function in JavaScript?

Question

I want to make a function that add an item to my localStorage object. E.g.:

alert(localStorage.getItem(\'names\').addItem(\'Bill\').getItem(\'names\'));
         


        

Answer 1

getItem('names').addItem('Bill').getItem('names')

I am confused, how do you get an item that has not been added???

getItem returns an object contains addItem method, and addItem method returns an object contains getItem method

Anyway, have a look the following tutorial. It does not completely solve your problem, but will give you an idea.
