Write Higher Order Arrow Functions (choose only integers without fractions)

Tell us what’s happening:

Hello experts! Could you help me, please? Unfortunatelly, I can’t understand how I should choose only integers without fractions. Give me an advice, please.

Your code so far

const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34];
const squareList = (arr) => {
  "use strict";
  // change code below this line
  const squaredIntegers = arr.filter(numbers => numbers > 0 && ....????...... );
  // change code above this line
  return squaredIntegers;
// test your code
const squaredIntegers = squareList(realNumberArray);

I think you can make use of the Number.isInteger() check. You can look it up to see what it does and try.

Thanks Hbar1st! I supposed that I should use Number.isInteger(). But how should I use it correctly in my sample?
And should I create a new variable for this purpose?
