Problem in Higher Order Functions

Tell us what’s happening:
When I was stuck in a problem then try to get help as “Hint” and at the end the same copy and paste the code from hint section and tried to execute code again but still it’s not working.
Kindly help me to get out of this problem.

Your code so far

const squareList = (arr) => {
// Only change code below this line
const squareList = arr => {
return arr.reduce((sqrIntegers, num) => {
  return Number.isInteger(num) && num > 0
    ? sqrIntegers.concat(num * num)
    : sqrIntegers;
}, []);
// Only change code above this line

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

Challenge: Use Higher-Order Functions map, filter, or reduce to Solve a Complex Problem

Link to the challenge:

you have a function definition inside a function definition, the outher function doesn’t return anything, the inner one is never called

Yes got it, Thanks for support:-)
