# Help needed for this topic :Write Higher Order Arrow Functions

Tell us what’s happening:
I can’t seem to figure out what is going wrong with this code. I have set the squaredIntegers array to [16,1764,36] but i can’t seem to figure out where to use the filter , map or reduce function. Help would be really appreciated . Thanks.

``````
const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34];
const squareList = (arr) => {
"use strict";
// change code below this line
const squaredIntegers = [16,1764,36];
// change code above this line
return squaredIntegers;
};
const squaredIntegers = squareList(realNumberArray);
console.log(squaredIntegers);
``````

Eheh man, you can’t just write the solution in plain text and expect to pass the challenge
What you’re supposed to do is to use high order function ( i.e. filter, map, reduce ) to obtain the result you wrote.

How to do that? Well, to summarize the challenge instructions you have to do two operation:

• Check for each element of the array passed as argument to the squareList function if it is an integer
• Return the square of each integer

Using those HOF could help

Oh Ok… yea that’s true

Well i got it just now and pass the challenge. Thanks for the help anyways.
