I am trying to see if a KEY is stored in the users localStorage, but I every code I seem to try either says its always found regardless of whether its there or not.

if (localStorage.getItem(2) === null) {
  alert('not found');
} else {
    alert('Found!');
}

The key is the number 2, I have tried wrapping the number in double quotes but regardless of whether the key is there or not it always says its found.

@morten.c I've used the answer in the question listed, it does not fix the issue. – InvalidSyntax Apr 01 '14 at 01:22
what dies calling getItem with an integer return then? – Mike Cheel Apr 01 '14 at 01:34
It will return a stringified array – InvalidSyntax Apr 01 '14 at 01:50
