Tell us what’s happening:
When i execute the program i get 2 errors:
squaredIntegers should be an array
squaredIntegers is undefined
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 squareIntegers = arr.filter((num) => (num === Math.floor(num))).map((num) => (num * num));
// change code above this line
return squaredIntegers;
};
// test your code
const squaredIntegers = squareList(realNumberArray);
console.log(squaredIntegers);
