Interesting explanation. When I last checked that the "!+[1,]" expression alone was coherent across all the browser but "if(!+[1,])" statement was not.

I think there is something weird about the parsing of the comma in "if" statement in old IE.

Correction. There is nothing special in "if". IE9 is just different, as you explained.
