How to check if an Array is Empty in Ruby - Step by Step Examples

How to check if an Array is Empty in Ruby ?

In Ruby, you can check if an array is empty using the empty? method.

In this example,

We create an array named numbers with some elements.
We check if the array is empty using the empty? method and store the result in the variable is_empty.
Finally, we print whether the array is empty or not.

numbers = [1, 2, 3]
is_empty = numbers.empty?
puts "Array is empty: #{is_empty}"

Array is empty: false

In this example,

We create an empty array named empty_array.
We check if the array is empty using the empty? method and store the result in the variable is_empty.
Finally, we print whether the array is empty or not.

empty_array = []
is_empty = empty_array.empty?
puts "Array is empty: #{is_empty}"

Array is empty: true
