How to remove the last element of an array in Ruby

In this tutorial, we are going to learn about how to remove the last element of a given array in Ruby.

Consider, we have the following array:

prices = [10, 20, 30, 40]

Now, we want to remove the last element 40 from the above array.

Removing the last element

To remove the last element of an array, we can use the built-in pop method in Ruby

Here is an example, that removes the last element 40 from the prices array.

prices = [10, 20, 30, 40]

prices.pop

puts prices

Output:

[10, 20, 30]

Similarly, we can also use the delete_at() method to remove the last element.

prices = [10, 20, 30, 40]

prices.delete_at(prices.length-1)

puts prices

Output:

[10, 20, 30]

Note: The pop() and delete_at() methods modifies the original array.
