Tell us what’s happening:
Code test is failing, telling me “loop should not be used.”
I see no loop.
I clearly missed the requirement that the number has to be greater than zero, but even when I just copy in the code from the solution (heresy!) I still get the no loop error.
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
// use filter to check for integers, then map the results to square them.
const squaredIntegers = arr.filter(num => num % 1 === 0).map(num => num * num);
// change code above this line
return squaredIntegers;
};
// test your code
const squaredIntegers = squareList(realNumberArray);
console.log(squaredIntegers);
