# Below are some examples of what I love about Ruby

# Code that reads like English
10.times { print 'Hello' }

this_variable_is_true = true
print 'Something' if this_variable_is_true

# Metaprogramming
class Integer
  def hundred
    self * 100
  end

  def thousand
    self * 1000
  end
end

class Enumerator
  def print(string)
    loop do
      puts string
      self.next
    end
  end
end

puts 10.thousand # prints 10000
1.hundred.times.print 'Wow!' # prints 'Wow!' one hundred times

# Powerful standard library
puts [*(0..9)].permutation(3).to_a.length # prints the number of permutations of length 3 for 0-9
