additionally taken from the below link -

lambda handles arguments exactly as a Ruby method; pass less or more arguments than the function expects, and you get an ArgumentError. Proc.new tolerates errors; if you call it with less arguments than specified, the rest are set to nil; if you specify more, the ones in excess are ignored.
