Tell us what’s happening:
What should I do exactly in this challenge?
What I should include either in map or filter or reduce to perform:
squareList([4, 5.6, -9.8, 3.14, 42, 6, 8.34, -2]) should return [16, 1764, 36]

(As I said, I don’t understand the challenge so I did not change the code)
Your code so far


const squareList = arr => {
// Only change code below this line
return arr;
// Only change code above this line
};

const squaredIntegers = squareList([-3, 4.8, 5, 3, -3.2]);
console.log(squaredIntegers);

read the requirements - it asks to return an array that contains the square of the positive integers in the input, do you get why each of the elements in the input is there?
