I've wroten this localStorage wrapper because noticed that every method throws exceptions.

Here is some examples.

Method localStorage.setItem throws follow exceptions:

  - Chome:

    code: 22

    message: QUOTA_EXCEEDED_ERR: DOM Exception 22

    name: QUOTA_EXCEEDED_ERR

    

  - Firefox:

    code: 1014

    name: Persistent storage maximum size reached

    message: NS_ERROR_DOM_QUOTA_REACHED

  - Interner Explorer:

    code: none

    name: none

    message: Not enough storage is available to complete this operation

Unknown and undocumented exceptions of other methods (some examples, most of them I catch from Firefox and IE):
