What are the advantages of "var" over "let"?

In my opinion, it is necessary to clean up the code I mean console.log, but in my opinion the solution is interesting)))

Maybe it is better to use var instead of let?

My bad

Come on, spoiler flags please!

I think const is better

You can remove comment btw

Thank you. I agree with you. I have just fixed it.

Thank you! I will fix it.

Thank you!

Remove unnecessary parentheses

how can we avoid loop inside in the solution?

please, use let
