Well done👌🏻

Yes

Forgot that we can change everything to make it look good! Nice and Clean!

:o

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.

LoL, this is mega beautiful and laconic, I would never have thought of this myself 🙃

First argument — the starting index, Second argument — the ending index (not included in the result)

why is it 1 and not 0, -1?

Woooow

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

thats what I wanted to

ahh right ur clever
