The square of positive numbers from an array.js

const squareList = (arr) => {
  // Only change code below this line
  if (Array.isArray(arr)) { // check if the arr is an arrat
    console.log('hello world')
    arr = arr.filter(element => typeof parseInt(element) == 'number')
      .filter(element => element > 0 && element.toString().indexOf('.') == -1)
      .map(element => element ** 2);
    console.log(arr)
    return arr;
  }else
    return 'OOPS arr is not an Array!'
  // Only change code above this line
};

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