Do you think so? It increases the dependencies but it reduces the implementation code itself.
I tend to think that as long as the code is clear it might make sense.

You also don't need to compute the index modulo, just use a boolean as a flag.

I like your solution. is not the fastest but easy to read! good job!

def not best practice for something this simple. if you can avoid using a lib do it.

lololol

doing this excersie i reliase you could have used indexOf(), .includes(), and .search(). First time i heard of search tho

Use spoiler flag next time.

=== instead of == is better practice

i wouldn't call this best practice do
