Sorry mate, you're just mistaken.

I am afraid that the way you described is not the way they work. The
condition is evaluated before the loop starts and only commences if the
condition is met. So will not run at
all.

Also it is quite easy to test if the dynamic.value will be above zero.
E.g
Do loop
Do something else

Yes Adam it does, I had to change much code back in the day due to that
very issue.

Nah, the condition is checked, but the code within the loop is not
Because your output is on the outside of the loop, therefore 2 is expected.
That is not an indication your loop is running twice, and to confirm that
you will need to put the output inside the loop and you will see a big
difference.

The.simple answer is, only use an index loop where there is more than 1
iteration. It will always run once even if the loop is 0, because it has to
run once to find that out.
I have never had an issue with an interation of 1 running twice though,
that I have noticed anyway.

The expressions passed to tags are evaluated first, then passed into the
tag code. So in this case it's not the expression "arrayLen(someArray)"

It's the way index-based loops work. At the first pass of the , the
INDEX variable is created with the initial value, and the condition (in
this case the condition is an implicit "index variable value <= TO value").
If the condition is true, the loop block is entered. At the bottom of the
loop blo
for (var j = 1; local.j lte ArrayLen(local.somearray); local.j++) {
WriteOutput(local.j);

Not sure, but I believe the index at loop completion is incremented - that's
how it knows how to stop. So it's similar to
j=1;
while(j<2) {
j++;
}

Why are you looping from 1 to 1? That isn't a loop.
