Use while true instead of loop RB-P1002

loop can be upto 3x times slower than using while true for unbounded loops.

Bad practice

def slow
  index = 0
  loop do
    break if index > NUMBER
    index += 1
  end
end

Recommended

def fast
  index = 0
  while true
    break if index > NUMBER
    index += 1
  end
end
