  1. // fastest way to iterate through a loop
  2. // - set var to :int
  3. // - count down from desired loop count to zero
  4. // - on each count we test the Boolean value of j (j<1 makes it false)
  5. // - instead of counting down with j-- we use j += -1 because adding negative
  6. //   numbers is faster than subtracting
  7. //
