What is “for” in Ruby

Hey. My question is if these loops are the same when I iterate through an Array. Thx for your time!

<% for track in @tracks %>

or

<% @tracks.each do |track| %>

Answer 1

They are different (although it may not matter for your purposes).

for doesn’t create a new scope:

blah = %w(foo bar baz)
for x in blah do
   z = x
end
puts z # "baz"
puts x # "baz"

.each creates a new scope for the block:

blah.each { |y| a = y }
puts a # NameError
puts y # NameError
