# RemoveAll proc (list)

Source: https://ref.dm-lang.org/list/proc/RemoveAll
Added in BYOND 515.

### Format
> `list.RemoveAll(Item1,Item2,...)`

### Returns
> Number of items removed.

### Args
> One or more items to remove entirely from the list.

Removes all copies of the specified items from the list. If an argument is itself a list, each item contained in it will be removed.

This is basically a faster version of the statement `while(list.Remove(Item1,Item2,...))` with an empty code block. For large lists this might be a big improvement because the list doesn't have to be traversed every time.
