1.class vs method1.class

ruby-talk
1

so 1.class will give Fixnum...

but when i define a method

def foo
  puts "ha"
end

how can i invoke

foo.class

as it is taking what foo returns... as then invoke class on that.

>> def foo; end
=> nil
>> method(:foo).class
=> Method

Hope that helps.

becouse foo returns what puts returns and it's nil, and nil have NilClass

you have to understand that in ruby EVERYTHING returns value (even if it's nil) and everything is object (even nil)
