*Tell us what’s happening:
I can’t tell if I am lost, or if the course just accelerated past me…
I understand everything leading up to this, but when we hit this problem I feel that a bunch of stuff was required to solve the coding example hasn’t been presented previously. Like Math.pow…
Is this a sink or swim thing or did I miss something I can’t find going back to look at previous sections.

Your code so far


const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34, -2];
const squareList = (arr) => {
  "use strict";
  // change code below this line
 squaredIntegers.filter = arr;
  // change code above this line
  return squaredIntegers;
};
// test your code
const squaredIntegers = squareList(realNumberArray);
console.log(squaredIntegers);

There’s an FCC YouTube video that may help you out entitled “Arrow Functions - Beau teaches JavaScript” (I’m too new to post the url)

The first hint I could offer is that your syntax is off on what you have so far, it should look like this

const squaredIntegers = arr.filter(
