I'm not sure what I'm doing wrong? Such a simple thing! Defining Ruby Methods.

Trying to define a Ruby Method...

method.rb 
def hey(hello)
  puts "hello"
end

Hello, Kody

  • method name needs to be hello
  • and it takes 1 argument.

Your code is almost correct, change your method name from hey to hello; and change the name of the argument from hello to something else, because you can't have method and argument sharing the same name. Then your code should work.

def hello(arg)
end

Hey Kody,

You have an argument that doesn't do anything.

Now if you have:

def hello(hey)
puts hey
end

Then you can put hello("Hello") then it will output "Hello" in the console, but

def hello(hey)
puts "Hello"
end

Doesn't use that hey argument. Arguments are basically like variables you can pass through the function.
