fizzbuzz_class_solution.rb

# The initial solution looked like this:
(1..100).each do |x|
  
  puts x
  
  if x % 3 == 0 && x % 5 == 0
    puts "FizzBuzz"
  elsif x % 3 == 0
    puts "Fizz"
  elsif x % 5 == 0
    puts "Buzz"
  end
  
end


# Then, after some refining, it looked like:
(1..100).each do |x| 
  div_by_three = (x % 3 == 0)
  div_by_five = (x % 5 == 0)

  if div_by_three && div_by_five
    puts "FizzBuzz"
  elsif div_by_three
    puts "Fizz"
  elsif div_by_five
    puts "Buzz"
  end
end


# And finally, after even more refining:
(1..100).each do |x| 
  div_by_three = (x % 3 == 0)
  div_by_five = (x % 5 == 0)

  output = ""

  if div_by_three
    output += "Fizz"
  end

  if div_by_five
    output += "Buzz"
  end
  
  if output.length > 0
    puts output
  end
end


# This is beyond what was covered in class, but it turns out you can also write if
# statements at the end of a line, and that line won't get run unless the if statement
# evaluates to true. So, we could actually take our code one step further:
(1..100).each do |x| 
  div_by_three = (x % 3 == 0)
  div_by_five = (x % 5 == 0)

  output = ""
  output += "Fizz" if div_by_three
  output += "Buzz" if div_by_five

  puts output if output.length > 0
end
