This question is more of a interesting concern.
I have some modularized code. In this code, I pass an array reference to a function which returns a different array as a reference.
use ModuleName qw(moduleFunction);
@arrayPassedIn = qw(some values here);
#there are 9 values, to be specific.
$return = moduleFunction(\@arrayPassedIn);
@arrayToPrint = @$return;
For reference to module function looks like:
$input = shift;
@arrayToBeManipulated = @$input;
#manipulations occur here producing a new array with 6 values;
@newArray = qw(6 unique values);
So here is the kicker. When I print @arrayToPrint, I get the 6 values that I desire, and then the last 3 values of the array I passed into my function. Is this as intended? Am I doing something wrong? It doesn't effect my code, because I just discard these values, but I am curious what is going on.
P.S. this is my first post on here. If I am violating any rules, I apologize in advance. Also, if you see a simple way I can improve my conventions for coding, I am largely self-taught and happy to learn and improve!
