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

Now that you have worked through a few challenges using higher-order functions like `map()`, `filter()`, and `reduce()`, you now get to apply them to solve a more complex challenge. # --instructions-- Complete the code for the `squareList` function using any combination of `map()`, `filter()`, and `reduce()`. The function should return a new array containing the squares of *only* the positive integers (decimal numbers are not integers) when an array of real numbers is passed to it. An example of an array of real numbers is `[-3, 4.8, 5, 3, -3.2]`. **Note:** Your function should not use any kind of `for` or `while` loops or the `forEach()` function.
