Wut?

why always double circulate is the top Best Practices？ seriously?!

once circulate is OK !

I used let keyword here it failed some tests, I had to change, check mine.

This is neither clever nor best practices in my humble opinion.

? true : false is redundant here.
The strict equality operator (===) checks whether its two operands are equal, returning a Boolean result.
And in our case, if two conditions are true, Logical AND (&&) will return true, otherwise false

Substandard solution

O(n^2) definitely not the best practice

LMAO SAME

Very impressive. I've learned a TON from my insane attempt and then seeing this.

Great solution! I added an unneccessary break instead of just return the result when i found it.

the best one.
