i know it's shitty code, but it works

x,D

beautiful

In case of one test this one is good !!!

best solution

as required

No, this isn't required anywhere. 2 empty arrays are "same" (they are not null)

Input:

array(0) {
}
array(0) {
}

Therefore I'm returning false (as required) and I'm getting this:

Failed asserting that false matches expected true.
Expected: true
Actual  : false

Sorry if I'm still not getting something.

Nothing broken. Before posting issues look at the top of the page: 17364 guys passed the JS kata. Sorry but your code is wrong.

17364 JavaScript completions

Showing the input without the error message for it is useless. All the tests are correct, not an issue.

And many were shown the tests are fine. Print something besides the input values. Like this:

  echo "a1: \n";
  print_r($a1);
  echo "a2: \n";
  print_r($a2);

Sorry, but given I can see the output (and the tests), I cannot confuse anything here. As far as I can see, many user reported this as failed.

Read this: https://docs.codewars.com/training/troubleshooting/ you're probably confusing a test case with another one.

Let me clarify:

• basic tests are OK
• testBasics is failing at the second case

Checked it in my local env as well, with the very same input (and solution, of course).
