I was only really referring to automatic type conversion for comparisons. That said, the example you gave sounds like the opposite, where you wanted it to do some auto-conversion and you're disappointed that it didn't? If I did 1 + "10" I don't think I'd want it to return 11!
It did convert the value. It converted the 1 to a string and added "10" to the end of it, resulting in "110" which then was converted to a float and used.
The error in this case would be forgetting Javascript's rules of implicit conversion.
