How to Iterate Over an Array in Reverse Order in Ruby ?

Answer

To iterate over an array in Ruby in reverse order, you can use the reverse_each method or a for loop starting from the last index to the first index.

✐ Examples

1 Iterate Over Integer Array in Reverse with reverse_each Method

In this example,

We create an integer array named numbers with some values.
We use the reverse_each method to iterate over each element of the array in reverse order.

Ruby Program

numbers = [1, 2, 3, 4, 5]
numbers.reverse_each do |number|
    puts number
end

Output

2 Iterate Over String Array in Reverse with for Loop

In this example,

We create a string array named fruits with some values.
We use a for loop starting from the last index to iterate over each element of the array in reverse order.

Ruby Program

fruits = ["apple", "banana", "cherry"]
(fruits.length - 1).downto(0) do |i|
