Ruby: Removing nil Elements from an Array

To remove nil elements from an array in Ruby, you can use the compact method. The compact method removes all nil elements from the array and returns a new array without those elements. Here's how you can do it:

array = [1, nil, 2, nil, 3, nil]
new_array = array.compact

In this example, new_array will contain [1, 2, 3], without the nil elements.

Let's break down the steps:

1. Create an array with nil elements: ruby array = [1, nil, 2, nil, 3, nil]

2. Use the compact method to remove nil elements and assign the result to a new array: ruby new_array = array.compact

The compact method removes all nil elements from the array and returns a new array without those elements.

1. The resulting new_array will contain only the non-nil elements: ruby puts new_array # Output: [1, 2, 3]

The new_array will contain [1, 2, 3], without the nil elements.

That's how you can remove nil elements from an array in Ruby using the compact method.
