# contents list var (world)

### Default value
> List of all areas, turfs, mobs, and objs initially in the world.

This is a list of every object in the world. Objects in this list are in no particular order.

```dm
proc/ListAreas(mob/M)
  var/area/A
  M << "Areas:"
  for (A in world.contents)
    M << A
```

This example displays a list of every area in existence. As a convenient short-hand, one may simply write for(A) or for(A in world) instead of the full for(A in world.contents).
