why do I need the @ for setting variable value
- by Saad
I'm a little confused about scope of variables, in ruby I wrote a test program:
class Test
attr_reader :tester
def initialize(data)
@tester = data
end
def getData
tester
end
end
puts Test.new(11).getData
now this works fine, the attr_reader, but my confusion is that since I've define attr_reader :tester then why can't I go tester = data rather then @tester = data, because when retrieving the data in getData I only have to write tester and not @tester
