I have got a bug with some javascript code that it's hard to reproduce (so no jsfiddle, sorry). Exactly the same browser (FF 37.0.2), but two different machines, and I can only reproduce the bug on one of them.

I suspect the issue has something to do with localStorage and the fact that I check if an item is there outside $(document).ready().

Is that required? Do I need to wait for the DOM to be ready before reliably accessing localStorage? Is my hypothesis plausible?

localStorage is not something that needs to be "loaded" asynchronously. It is available the moment the page starts to load and can be used by Javascript anywhere in the page. If the browser has to fetch values form somewhere (e.g. the disk), that is done synchronously when you request the data or before.

There is no need to wait with $(document).ready() before accessing localStorage. The cause of your issue must be something else.

FYI, you can read the spec on WebStorage here: http://dev.w3/html5/webstorage/#dom-localstorage. There is no indication in the localStorage section of that document that JS code must "wait" before accessing.
