Write Higher Order Arrow Functions!

Tell us what’s happening:

It gives “num” is not defined.
How should i define “num”??

Your code so far

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 = arr.filter((num) > 0 && Number.isInteger(num)).map(num => num*num);
  // change code above this line
  return squaredIntegers;
// test your code
const squaredIntegers = squareList(realNumberArray);

filter requires a function, not an expression as argument.
