It solves a task the content of which is as follows:

This kata is from check py.checkio.org

You are given an array with positive numbers and a number N. You should find the N-th power of the element in the array with the index N. If N is outside of the array, then return -1. Don’t forget that the first element has the index 0.

Let’s look at a few examples:

```
array = [1, 2, 3, 4] and N = 2, then the result is 3^2 == 9;
array = [1, 2, 3] and N = 3, but N is outside of the array, so the result is -1.
```

and here is my code

```
function index(array, n){
let result;
if(array.indexOf(array[n]) == n) {
result = Math.pow(array[n], n);
}else{
result = -1;
}
return result;
}
```

I know that someone gave the same task here, but I do not want to copy someone’s solutions, so I am asking for help

Hello and welcome to the freeCodeCamp community~!

While we are primarily here to help people with their **Free Code Camp** progress, we are open to people on other paths, too. *Some* of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at https://www.freecodecamp.org/learn.

With your current questions, we don’t have enough context to know **what you already know or don’t know**, so it is impossible to guide you without just telling you the answer (**which we won’t do**).

It is pretty typical on here for people to share a codepen / repl.it / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding
