Is there a functional style of doing a do while (so that I don't have to create a variable before entering loop)?  Basically I have an array and I generate a new array with 1 less element, when no more elements or the array is in the desired state the loop is done.

it uses the previous array to generate the new one

What about using the `.filter { … }` operator on a list?

not sure what you mean, how would it work?

oh maybe it can work. if I do (1...sizeOfArray).filter { calculate  and return 0 }. but I can't exit early

and can't pass new array to next calculation

some example code might help to see what you're trying to do

There are `takeUntil` and `takeWhile` operators as well.
