🔑 Accessing Values Safely

Accessing a non-existent key returns nil, so you must handle missing keys to avoid unexpected errors. Use the safe navigation operator or check for nil before working with the value.

inventory = { apples: 10, bananas: 5 }
stock = inventory[:oranges]  # => nil

if stock.nil?
  puts "No oranges in stock"
else
  puts "We have #{stock} oranges"
end
