change = {status: “INSUFFICIENT_FUNDS”, change: []};

I would expect this uncommented test to return insufficient funds
as it is I’m passing 3 out of the 6 test
but due to how javascript handles decimals
I’m afraid I’ve lost scope of where I have scaled up or down 2 digits
and where it affects a conditional comparison

#2

This challenge is a bit misleading.
In this case there are sufficient funds BUT the cash register does not have the correct denominations remaining.
Try to test for this situation.

My solution after all other tests are done, ends with:

   // Handle denomination for exact change not available
   if (changeLeft > 0) {
     return 'Correct change not available';
   }
