const challenge = array => {
  let elements = array;
  let newArray = elements;

  for (let i = 0; i < array.length + 1; i++) {
    let [first, second] = newArray;
    let sumTwoFirstElements = first + second;

    newArray.splice(0, 2);
    newArray = [sumTwoFirstElements, ...newArray];
    console.log(newArray);
