Tell us what’s happening:
Well, I don’t knwo how to compute the square of only the positive integers. Can somebody explain for me? Thanks in advance.

Your code so far

``````
const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34, -2];
const squareList = (arr) => {
"use strict";
// change code below this line
const squaredIntegers = arr.filter((num) => num > 0 && parseInt(num) === 0)
// change code above this line
return squaredIntegers;
};
// test your code
const squaredIntegers = squareList(realNumberArray);
console.log(squaredIntegers);
``````

You can use isInteger method to check if a number is integer or not.

I would run a map method before your filter and trim your array down to integers first.

Thank you. I figured it out.
