What's not clever about it?

Ah thats clever thinking

redacted

names.length should work for an array, I have just used it to complete this challenge.

I can see in your submitted solution you have tried to assign the length of names array with names.length(); (you have a typo in length), .length() will only work for a string in the array, not an array of strings. You need to use .length

Sorry to comment 2 years later but why did you get downvoted here lol so weird

Relatable haha

Why wouldn't you use a built in method?

I learned this formula in my Math class recently. Look up Sigma notation.

Then you should start using one lol
