can you tell the order in which website should be madeby beginners to learn ruby ..like blog, comercial?

[Kewendi]

My code was:

count = states.count
while count > 0 
puts states[count -1]
count -=1
end
puts "End"

This worked perfectly. Is it wrong because I haven't put the -1 after states.count?
