# JSON_DELETE

*LSL constant*

```lsl
string JSON_DELETE = "\\u{FDD8}";
```

A [constant](https://wiki.secondlife.com/wiki/Category:LSL_Constants) used to delete a value within a [JSON](http://www.json.org/) text string.

## Caveats

- Using `JSON_DELETE` will **not** prune empty objects or arrays at higher levels.
- Using `JSON_DELETE` to delete a non-existent array or object element in a JSON string will return [JSON_INVALID](/constants/JSON_INVALID/), not an unaltered string.

## Examples

<details open>
<summary>Example 1</summary>

```lsl
default
{
    touch_start(integer num_detected)
    {
        string jsonString = "[1,2,3,4,5]";

        llSay(PUBLIC_CHANNEL, "Original: " + jsonString);

    //  we remove the first item (list has zero-based index!)
        jsonString = llJsonSetValue(jsonString, [0], JSON_DELETE);

    //  "[2,3,4,5]"
        llSay(PUBLIC_CHANNEL, "Modified: " + jsonString);
    }
}
```
