Oh god. It was really painfully. I sat with this problem for several hours(about 4-5).
As a result, the error was that fetch(url) should ALWAYS come immediately followed by ".then()".
You can't write

  let promise = fetch(`...`);
  promise.then(...)
  return promise

But I dont know why. May be it is related with a microtasks stack? If there is anyone who knows, please tell me the topics that I could read

Nice kata, it made me remember Date object

Oh god:0

This kata only supports up to node 8 and the ?? operator was introduced in node 14.

What is wrong?

/home/codewarrior/index.js:7
    calculate.counter = calculate.counter ?? 0;
                                           ^

Im sure that my function works... ??- defines whether variable is defined, if this one doesn define so its takes value after??` sign

Oh God. You are right))

It says minimal, and 0 < 1.

why for 0 handshakes amount of partisipants have to be 0? It might be 1 participant... Just due to this inaccuracy in test my code isnt beautifull :c

Thanks) I decided task. I was really confident that return first one :) yack inattention

Add the example in the description to the sample tests in all languages.

Yes, I've seen it, and no, you're not returning the first one, try the example in the description:

testing(longestConsec(["tree", "foling", "trashy", "blue", "abcdef", "uvwxyz"], 2), "folingtrashy")

Have you seen my code(Im a newbie and really dk)? Im sure, im returning the first consisting. I have checked it by different cases> for example :
longestConsec([ab, cdefgh, 1, 2, 3, jk, lmnopq ], 2).
And all work correct. Im confused :( By the way i think yoy are right, thanks for cheking, will take more efforts

The input is an array of strings, that's not the problem (I've added the quotes to the error message). Your code is wrong. Not a kata issue.

Your task is to return the first longest string consisting of k consecutive strings taken in the array.

You're not returning the first one.

Wrong random test! I cant resolve task due to argiments arent a string type in the test.
An error I have seen below:
