Method Call

Method calls in Goby looks like:

[1, 2, 3].first

foo.bar

"String".split("r")

The object before . is the receiver, and the identifier after . is method name. Receiver can be any kind of objects, including a special expression self, which returns the current scope object.

class Foo
  def self.bar
    10
  end

  puts(self.bar) #=> 10
end

But you can also avoid using self, the method will automatically consider self as receiver if no receiver is specified.

class Foo
  def self.bar
    10
  end

  puts(bar) #=> 10
end
