`localStorage in window`
=> checks if "localStorage" is specified in window object
`window.localStorage !== null`
=> checks to make sure that "localStorage" is not a null object (i.e.,
typeof null === 'object')
I don't think we need both. IMHO the following should suffice:
`!!window.localStorage`
null and undefined are both _falsy_, so I don't see why the above shouldn't
work.
