➕ Adding Elements

To grow an array, use push or the shovel operator (<<) to append, and unshift to prepend. These methods modify the array in place and return the array itself, making chaining possible.

numbers = [2, 3]

# Append to end
numbers.push(4)    # => [2, 3, 4]
numbers << 5        # => [2, 3, 4, 5]

# Prepend to start
numbers.unshift(1)  # => [1, 2, 3, 4, 5]
