Needed a simple way of telling me how many of each letter I needed to cut on the laser cutter

letter_counter.rb

def letter_count(str)
  str.chars.each_with_object({}) do |char, hash|
    next if char == " " # skip spaces
    hash.store(char, 0) if hash[char].nil?
    hash[char] +=1
  end
end

letter_count("hello world").each { |char,count| puts [char, count].join(" == ") }
