Is there any difference between: window.localStorage and localStorage?

Question

I have been doing the following:

var store = window.localStorage;
store.setItem()

but now I see code doing this:

localStora         


        

Answer 1

Supposedly, window.localStorage makes the localStorage faster to be found than just writing localStorage.

Storing a reference to it on a variable makes it even faster.

Anyway, these improvements are negligible on modern browsers. It only becomes useful if performance is being an issue.
Anyway, you get a possible idea about why it is being done like that.
