While testing, I received the following message:

Testing "D Gb B", expecting "Not a chord", 'Minor' should equal 'Not a chord'.

But this is B-minor chord! The order of the steps is simply rearranged here. Who taught you music theory, my friend? )))

Thank you for your help. But why, when [true] x11 and the XOR operation, do I get the error: “expected false to equal true”? I didn't change the initial data in any way.

...That isn't how multi-input XOR works. it works like this:

If at least one input is true, return true,
EXCEPT if all inputs are true, then return false.

in your case, all the inputs are true, which means that XOR will return false.

Can anyone explain to me why when [true, true, true], XOR = false?
This is literally:
(true XOR true) XOR true = false XOR true = true

Oh. Thanks for the clarification!

If you're talking about JS, then no. It's simply a built-in function that casts your variable to a boolean.

Damn Boolean is a keyword?

So true!

Thanks!

LGTM. Approved
