Hi. I work on Firebug, a web page debugger for Firefox
(http://getfirebug.com).
In attempting to show developers relevant information about all objects
in their program I was trying to display window.sessionStorage. In the
process I read the document http://dev.w3.org/html5/webstorage/. I found
the document unnecessarily confusing because it uses the property
'length' for Storage. This is the same property used by Javascript Array
type, but Storage is not an array and you cannot enumerate the elements
of the Storage object |s| using
for(var i = 0; i < s.length; i++)...
Any number of other names for the property would be equally effective
for your propose without confusing developers with a property that
implies array-ness. For examples, 'totalItems', 'numberOfItems', 'size',
'entries', or even good old 'n'.
Using the term "enumeration" to mean "property enumeration" is also
confusing, but I suppose ECMA script made that mistake too long ago.
