Write Higher Order Arrow Functions-- Why it does not pass the test?

Tell us what’s happening:

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(x => x > 0 && x%2 === 0).map(x => x*x);
// test your code
const squaredIntegers = squareList(realNumberArray);
