Just curious why my code isn't running. Do I need .each?
animals = ["dog", "cat", "horse", "goat"]
for animals do |x|
puts "#{x}"
end

for i in animals do puts i end

3,273 PointsWhen I change it to:
for animals.each do |x| I then get this error:
SyntaxError: e44c53dd-eb17-42e9-aa06-1533d8550b14.rb:21: syntax error, unexpected end-of-input, expecting &. or :: or '[' or '.'
What unexpected end of input? All the rest of the code remained the same.

7,110 PointsIf you remove the for in the block it will work. Calling each on that is all you should need :D
so
animals = ["dog", "cat", "horse", "goat"]
animals.each do |x| puts "#{x}" end

7,110 PointsYou are fantastic! Well done!
Sorry I didn't see the for loop requirement >.<
