I've read your comment about Crockforf and followed the link and he also says to use var the same way as you do :-)
"It is preferred that each variable be given its own line and comment. They should be listed in alphabetical order.
var currentEntry; // currently selected table entry
var level; // indentation level
var size; // size of table
I copied this code to JSLint and it passes. Seems Crockford changed his mind :-)
