How to start a subscript from an arbitrary number in Ruby iterative processing

Introduction

As the title says, it was personally convenient to start the subscript with an arbitrary number when repeating an array with each_with_index in Ruby, so I will leave it as it is.

manner

Just change ʻeach_with_index to ʻeach.with_index (n). Specify the start number for n. To start the subscript from 1, write as follows.

code

juices = ["tea", "cola", "coffee"]
juices.each.with_index(1) do |juice, i|
    puts "#{i}Third:#{juice}"
end

Output result

First: tea
Second: cola
Third: coffee

With ʻeach_with_index, it is necessary to set ʻi + 1, so this method is convenient.
