How to loop through an array using .each starting at an index in Ruby

Question

Ok, so we all know that you can do the following:

array.each{ |value|
    puts value
}

What if, however, I want to start at element n instead of starting at the beginning; ie n=0 .

Answer 1

你也可以

array.drop(n).each { |v| puts v }

Answer 2

You can call a subarray with a range like this:

array[n..-1].each { |value| puts value }

Where n is the index you'd like to start at, and -1 will always point to the last index of an array.
