| `elementId` | `elementId(value: Node\|Relationship) -> (string)` | Returns the identifier for a given node or relationship as a string. The identifier is the same as the one returned by `id()`. |
| `last` | `last(list: List[any]) -> (any)` | Returns the last element of a list. |
| `length` | `length(value: List\|string\|Map\|Path) -> (integer)` | Returns the number of elements in the value. When given a **list** it returns the size of the list. When given a string it returns the number of characters. When given a path it returns the number of expansions (relationships) in that path. |
| `nullIf` | `nullIf(value1: any, value2: any) -> (any)` | Returns `null` if the two arguments are equal, and the first argument otherwise. The arguments are compared as the `=` operator compares them, so a comparison that involves a `null` is undecided and the first argument is returned. |
| `properties` | `properties(value: Node\|Relationship) -> (Map[string, any])` | Returns the property map of a node or a relationship. |
| `propertySize` | `propertySize(entity: Node\|Relationship, property-name: string) -> (integer)` | Returns the total amount of bytes stored in RAM for the property of a given entity node or relationship. For more information, check [storage of properties inside Memgraph](/fundamentals/storage-memory-usage#calculate-storage-memory-usage). |
| `randomUUID` | `randomUUID() -> (string)` | Returns randomly-generated Universally Unique Identifier (UUID) |
