Thanks for building interesting kata, keep it up mate :)

Yeah totally agree !!!

You don't need extra space in character class, [\s]+ will do the same

Lol how come this is wrong advice ?

Just change to this and see

const wolfIndex = queue.length - 1 - queue.lastIndexOf('wolf');

It save extra looping which you do to reverse the array

There's no need of queue === ["wolf"] in first if condition

You can use lastIndexOf instead of reversing queue

Depends how much trdae off you like, i try to short only upto a point where it stays readable also.

Better in what sense ?
Both solution are same except number of characters, i wrote it so it stays readable also.

x:y

0 <= x <= 4
0 <= y <= 4

This is what the format is already described in question.

This is awesome :) that's why i love regex a lot :)

Sorry my bad i had some code commented out and because of that it was failing the some keywords are prohibited test.

I think . is also prohibited i am using Math functions and it's still failing keywords test.

How about . and , ?

I am solving this with the help of simple object, i am not using any of prohibited character why keywords test fails ?
is : is prohibited ?
