Description Anne 2009-04-15 14:42:56 UTC 
Since two out of three implementations of localStorage were unable to read the specification properly we have the unique (harharhar) opportunity to make the specification more in line with how ECMAScript works.

I.e. return undefined for nonexistent storage keys rather than null.
Comment 1 Ian 'Hixie' Hickson 2009-04-15 22:56:10 UTC 
The spec already says that Storage.missing should return undefined (see WebIDL). Are you saying you want Storage.getItem('missing') to also return undefined?
Comment 2 Anne 2009-04-16 10:09:37 UTC 
I would have much preferred that, yes. Seems too late now.
