The solution is the pass the arrays in the correct order to being with.
I posted about this the last time you asked:

  function doSomething(A, B) {
     return lessThan(A, B) ? reallyDoIt(A, B) : reallyDoIt(B, A);
  }

That's a terrible name.  A function the determines some property should
be named for the condition it tests.  If a function tests for an even
number, call it 'isEven', not 'checkParity'.  Call a prime tester
'prime' not 'check Divisors', etc.

But here, the function both determines some condition and the acts on
that condition.  It should be called 'swapIfLessThan' (or similar).

If you used a better name, the comment would be redundant, but even with
the comment I have no idea which way the test goes!

Stop wanting that!  Manipulating global objects makes for terrible code.
