π Usual way
books.each_with_index do |book, index|
puts "#{index}: #{book.title}"
end
#=> 0: a
#=> 1: b
#=> 2: c
π¦ Start from 1
You can use each.with_index(1)
.
This is good when you use each method in .erb file. Because users want to see index from 1 usually.
books.each.with_index(1) do |book, index|
puts "#{index}: #{title}"
end
#=> 1: a
#=> 2: b
#=> 3: c
