Which is the better option to use: localStorage(),

问题:

The question says it all. I realize that all options do work in up-to-date browsers, but what is the semantically best choice, and why?

Good question. According to W3C standards, the correct is window.localStorage because the localStorage attribute is part of window object. And it is not a function, it is an attribute.
