... "var true;" or "var (1==1);" wouldn't be valid, so there's no ambiguity about "var row=rows[i]" - it's obviously an assignment. The problem with for(var i...

Hope this might help someone- I use jslint in my build process from ant as well and it works great (although it's a really old version of jslint...) If you...
