RMMV Am I misunderstanding javascript/variables?

[DadGuyDrawing]

I have some code in a custom plugin where I place a bunch of arrays in $gameVariables but my code seems to replace all of the variables with the last array instead of placing them in sequentially.

Pseudo code:
-make a temp array with a bunch of 0's in it
-make a variable (intVariableID) with the first $gameVariable ID
-change a few items in the temp array
-place the temp array int the first $gameVariable with ID (intVariableID)
-change (intVariableID) to be the 2nd $gameVariable ID
-change a few items in the temp array
-place the temp array in the second $gameVariable with new ID (intVariableID)

I initially did this with a for ... loop, but all the variables were populated with the last array only. So I modified the code as per below, but still only the last array populates in all of the variables.

Any help would be appreciated! Actual code below.

Thanks.

        var arrTempStorageArray = [];
        var intBookShelfStorageVariableID; 
        
        /*:
        * Array Index
        0 = intTargetSkillID
        1 = intTargetIntroComplete
        2 = intTargetIntermediateComplete
        3 = intTargetAdvancedComplete
        4 = intTargetIntroSessions
        5 = intTargetIntermediateSessions
        6 = intTargetAdvancedSessions
        7 = intTargetIntroShow
        8 = intTargetIntermediateShow
        9 = intTargetAdvancedShow
        10 = intTargetTopicShow
        11 = Reward Screen

I think I got it. What does work with reassigning the intBookShelfStorageVariableID, does not work with arrays, as these are objects.

So this:

const a = [1, 2, 3]
a[4] = 4;
const b = a;

will result in BOTH a and b being [1, 2, 3, 4].

I recommend you to always use a new Array to mitigate unwanted side effects. So

$gameVariables.setValue(xy, array1);
$gameVariables.setValue(xz, array2);
$gameVariables.setValue(xv, array3);
...

And also I recommend to use shorthand assignment of arrays, ie.

const arrTempStorageArray = [0, 0, 0, 0, 0, 0, 0, 0, ....]

Wow that was fast! Thank you so much @Aerosys .
