Somewhat true, but to add to that... the 0 acts as a starting number, ensuring reduce behaves consistently. It prevents unintended type coercion and avoids errors when used on an empty array. So, while the 0 is optional if you are 100% sure the array is non-empty and contains only numbers, in all other cases, it's a good practice to include it.

Mad late, but hopefully helpful to future users: 0 is the initial value in the .reduce() method. As imaNami above said - it's totally optional and the code will still work without it.

It won't be about cuboids anymore if it has more than 3 elements. lol

Thanks for the solution. I get to know about the reduce() function for the first time from your code.

Daaamn.

Your points are not included in the array of your class's points. Do not forget them when calculating the average score!

You didn't take into account the length of your points

why?

lol, wont to start braind xD

chatgpt (not to be offensive)

My brain exploded when I saw how easy your solution looked lol

no @imaNami brother, there was a note said "Your points are not included in the array of your class's points. Do not forget them when calculating the average score!

". so you have to add it separately.
