Concise and clear!

Nice! Is this destructuring? Way neater than trying to keep track of indexes.

I came to say the same; better have one more variable for readability. Also, adding a comment to say why they're subtracting 96 would help for future maintenance. I agree its a nice solution.

This is a question of best practice. In my solution, I have two return statements in my function. The first checks the length and returns false if length is not 10, the other return statement checks if we finish at our starting position. Should I do the check for length and position in one return statement like I've seen in many solutions? It seems to me having that short-circuit check before I apply any other logic saves on computational work (however miniscule). Should I write functions with only return statement as general best practice?

Ah -- good point. I assume with these exercises that we'll get valid input (some exercises say to assume so). However, getting in the habit now would be wise. Thanks!
