[thelist] [javascript] for ... in - prevent certain properties from showing up

[apathetic]

Instead of using the associativeArray object detailed in your post,
how about using something like:

function countObject( obj ) {
    var len = 0;    
    for( var val in obj ) {
        len++;
    }
    return len;
}
