4. if…else…end -> ? :
5. (1..100).each do |i| print "#{i} " if i % 3 == 0 puts i % 5 == 0 ? 'fizzbuzz' : 'fizz' next end puts i % 5 == 0 ? 'buzz' : nil end count 148
6. nest conditional operator
7. (1..100).each do |i| print "#{i} " puts i % 3 == 0 ? i % 5 == 0 ? 'fizzbuzz' : 'fizz' : i % 5 == 0 ? 'buzz' : nil end count 122
8. do…end -> {…}
9. (1..100).each { |i| print "#{i} " puts i % 3 == 0 ? i % 5 == 0 ? 'fizzbuzz' : 'fizz' : i % 5 == 0 ? 'buzz' : nil } count 119
10. join lines
