# json.isArray

> Returns whether a value is treated as a JSON array by Real's JSON table detection.

Returns whether a value is treated as a JSON array by Real's JSON table detection.

## Syntax

```lua theme={null}
json.isArray(value: any): boolean
```

## Arguments

| Name    | Type  | Required | Description                                      |
| ------- | ----- | -------- | ------------------------------------------------ |
| `value` | `any` | Yes      | Value to inspect. Non-table values return false. |

## Returns

| Name      | Type      | Description                                                                                                                                                                         |
| --------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `isArray` | `boolean` | true when the value is a table marked as a JSON array or an unmarked table with contiguous positive integer keys from 1 with its maximum index. Empty unmarked tables return false. |

## Example

Check whether a table is treated as a JSON array by Real's JSON encoder.

```lua theme={null}
local items = json.array({ "one", "two" })
local record = json.object({ name = "Real" })
local inferred = { "one", "two" }

print(json.isArray(items))
print(json.isArray(record))
print(json.isArray(inferred))
```
