Checking if the number is Integer in Use Higher-Order Functions map, filter, or reduce

[luis.pellizzon]

Hello Guys, this is my first time posting something in FCC forum.
I just want to check if its ok to use the following code to check if the number is Integer. When I worked out the solution myself I couldn’t remember the method isInteger()

  Thats my code so far

const squareList = arr => {
 let newArray= arr
 .filter(num => num - Math.floor(num) === 0 && num > 0).map(num => num * num)
return newArray
};

const squaredIntegers = squareList([4, 5.6, -9.8, 3.14, 42, 6, 8.34, -2]);
console.log(squaredIntegers);

I belive this is right. There are multiple methods to solve a problem.
In your method you are using all these filter and map which maybe create hinderance for time complexity otherwise you are good to go.
