if (n >= 1 || typeof n === 'int'){:
Do you really want or (||)? Also, there is no int type in JavaScript.

First, if you put ```javascript before and ``` behind your code, it will be formatted like javascript code!

console.log("You see?")

This help analysing what you have coded.

Concerning your problem:

This is said in the kata's description:

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.

So besides the fact that you use Math.abs() I see no problem in your function isPrime(). Just remove this line of code:

num = Math.abs(num);

To avoid implementing the same piece of code multiple times, I checked wether start is smaller than end and therefore I declared two more variables. Now you can apply these to your loop like this:

var min = Math.min(start, finish);
var max = Math.max(start, finish);
for(var i = min; i < max; i++) {

}

At least, I don't quite know why you want to sort your primes. There is no need for this and it's only one more line of code which can cause an error...

Thanks! Glad you enjoyed it

The tests you see are just a small part of the whole thing that you get once you press "submit".

I edited this kata a bit, try it now :)

You should always add the error message if possible. That way, one can tell you whether it's a Codewars error or an error with your solution.

You're returning 'arr' inside the for block. You would have to put the return after the for block to make this work.
