# JSON.ARRPOP

> Pop value from JSON array.

Use `JSON.ARRPOP` to remove an element from the arrays a path selects and return it.

Without an index the last element is popped, which makes the command a stack pop; index `0` pops the first element, and negative indexes count from the end. An index past the end of the array is clamped to the last element. The reply is the removed element as JSON text, or null when the array is empty.

Because the read and the removal happen in one atomic step, a JSON array can be used as a small work queue without the risk of two clients taking the same element.

## Syntax

```redis theme={"system"}
JSON.ARRPOP <key> [path [index]]
```

## Arguments

| Argument | Required | Repeatable | Description                                  |
| -------- | -------- | ---------- | -------------------------------------------- |
| `key`    | Yes      | No         | JSON document key.                           |
| `path`   | No       | No         | Path selecting arrays; defaults to the root. |
| `index`  | No       | No         | Element index; defaults to the last element. |

## Important points

* Raw TCP examples pass JSON values as valid JSON text. Typed Upstash SDK helpers serialize native objects and values for you.
* Paths beginning with `$` use JSONPath and can match multiple values, so many JSON commands return an array of per-match results.

## 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-string JSON values or null values, one per matched path |
| RESP3    | Array of bulk-string JSON values or null values, one per matched path |

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

## Examples

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