In Ruby, you can use the include? method to check whether an array contains a certain element.
Here's an example code snippet:
fruits = ["apple", "banana", "orange", "kiwi"]
# Here, we're checking if the array 'fruits' includes the element "banana"
if fruits.include?("banana")
puts "The array includes 'banana'"
else
puts "The array does not include 'banana'"
end
This will output:
The array includes 'banana'
And here's another example:
numbers = [1, 2, 3, 4]
# We're checking if the array 'numbers' includes the element 5
if numbers.include?(5)
puts "The array includes 5"
else
puts "The array does not include 5"
end
This will output:
The array does not include 5
