JavaScript: Tips of the Day

Returns 1 if the array is sorted in ascending order, -1 if it is sorted in descending order or 0 if it is not sorted

Example:

const tips_Sorted = arr => {
  let direction = -(arr[0] - arr[1]);
  for (let [i, val] of arr.entries()) {
    direction = !direction ? -(arr[i - 1] - arr[i]) : direction;
    if (i === arr.length - 1) return !direction ? 0 : direction / Math.abs(direction);
    else if ((val - arr[i + 1]) * direction > 0) return 0;
  }
};
console.log(tips_Sorted([0, 1, 2, 2]));
console.log(tips_Sorted([5, 7, 3]));
console.log(tips_Sorted([8, 6, 4]));

Output:
