# ARLASTITEMS

> Read the most recently written array values.

Use `ARLASTITEMS` to read the values written most recently, without knowing where the cursor currently sits.

The command walks backward from the append cursor, wrapping to the end of the array when it passes index `0`, and collects up to `<count>` values. That wrapping is what makes it the natural reader for a ring built with [`ARRING`](/redis/commands/array/arring): it returns the current window in write order regardless of where the ring has wrapped to. On a plain array appended to with [`ARINSERT`](/redis/commands/array/arinsert), it returns the tail.

By default the values come back oldest-first, which is the order they were written in. `REV` reverses that, returning the newest value first. Slots that are empty come back as null, and `<count>` is capped at the number of values the array holds.

See the [array command overview](/redis/commands/array/overview) for the data model these commands share.

## Syntax

```redis theme={null}
ARLASTITEMS <key> <count> [REV]
```

## Arguments

| Argument  | Required | Repeatable | Description                                                                |
| --------- | -------- | ---------- | -------------------------------------------------------------------------- |
| `<key>`   | Yes      | No         | Array key targeted by the command.                                         |
| `<count>` | Yes      | No         | Maximum number of values to return. Capped at the number of values stored. |
| `REV`     | No       | No         | Return the newest value first instead of last.                             |

## Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

| Protocol | Reply                                       |
| -------- | ------------------------------------------- |
| RESP2    | Array of bulk strings and null bulk strings |
| RESP3    | Array of bulk strings and nulls             |

<Note>
  Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
</Note>

## Examples

TCP examples use the TLS `REDIS_URL` from the Upstash console. REST examples use `UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN`.
