My bad, I didn't get kata. I thought that they are equal. Thank you a lot.

Yep, you right, sorry for that.

I would have implemented your   suggestion but you cant change tests when more than 500 people have completed it. I do really appreciate feedback but dont you think saying, hey man, thanks for tha kata, I was struggling with seeing what went wrong with my tests when they failed, could you maybe please somehow print out the input data is better than I think the test description is bad? Learn how to have more respect when you complete someones work that they have done for a community for free at his own expense and time.

Because it is how tests should look like.

Hey, in my case one of the variables I was running .length on was indeed null. Fixed that and no error now.

same shit here

So you know how to print out and see all input data, you just want me to do it for you?

Why 0 0 1 1 1 0 / 0 0 0 0 0 0 1 should be drow?

Yep, I know that, but I just want to say, that appropriate test description is better.

You can do console.log to print out the args then you can see input data.

This tests has no description at all. So if it fail, it fail. All output is: Expect true to be false, and so on. And in this case you cannot check your kata, and verify it. Please add description like: "'xOxOx' should be false: failed, expect true to be false."
I'd like to see input data in submition tests too.

Thanks.

Any suggestions on how to improve it? Or do you like to just criticize without contributing anything?

I think that tests description is bad.
