🔄 Iterating Over Keys and Values

You can loop through hashes with each, each_key, or each_value. This allows you to process or transform data in your hash easily.

prices = { apple: 2, banana: 1, cherry: 3 }

# Full iteration
prices.each do |fruit, cost|
  puts "#{fruit.capitalize}: $#{cost}"
end

# Only keys
prices.each_key { |fruit| puts fruit }

# Only values
prices.each_value { |cost| puts cost }
