AkousaTypeError: Reduce of empty array with no initial valueArray.reduce() was called on an empty array without providing an initial value.
You called .reduce() on an array that turned out to be empty and did not provide an initial value as the second argument. Without an initial value, reduce uses the first element, but an empty array has no first element.
Always provide an initial value as the second argument to .reduce(): array.reduce((acc, val) => acc + val, 0). Check if the array is empty before reducing, or filter out empty arrays first.
