Tell us what’s happening:

I have some trouble to understand chaining methods. I totally gets what asked here : we need to use the filter method to check the number that are Number, but using the opposite of the method isNaN(), using a ! .

I just can’t figure out how to articulate that

Your code so far

const calculate = () => {
  const value = document.querySelector("#numbers").value;
  const array = value.split(/,\s*/g);
  const numbers = array.map(el => Number(el));
  const filtered = numbers.filter((el) => !Number.isNan(el));
}
