void
Throws
An error if either argument is not contained in this list.
moveBefore()

Move item so it is immediately before before in this list: places item at the index that before used
to occupy. Depending on the position in the list item originally occupied, some other items in the list may
shift to higher or lower indices as a result. No-op if both arguments are the same item.
Parameters
• item: T
• before: T
Returns
void
Throws
