# JSON_TRUE

*LSL constant*

```lsl
string JSON_TRUE = "\\u{FDD6}";
```

Return value for [llJsonValueType](/functions/llJsonValueType/) function indicating the data type of a given address specifier in a given string-serialized JSON object.

Also used to set the bare word 'true' as a Value within a JSON text using [llJsonSetValue](/functions/llJsonSetValue/) and [llList2Json](/functions/llList2Json/).

## Examples

<summary>Example 1</summary>

```lsl collapse={4-30, 36-42}
//  showing difference between JSON_TRUE & JSON_FALSE
//  and their LSL equivalents within a JSON text string

run_json_test(string input)
{
//  [true,false]
    say(input);

//  unicode equivalent of JSON_FALSE
    say(llJsonGetValue(input, [1]));

    input = llList2Json(JSON_ARRAY, [TRUE, FALSE]);

//  [1,0]
    say(input);

//  0
    say(llJsonGetValue(input, [1]));
}

say(string message)
{
    llOwnerSay(message);
//  llRegionSayTo(llGetOwner(), PUBLIC_CHANNEL, message);
//  llWhisper(PUBLIC_CHANNEL, message);
}

default
{
    touch_end(integer num_detected)
    {
        string TEST_STRING_JSON = llList2Json(JSON_ARRAY, [
                                              JSON_TRUE, JSON_FALSE]);

//      copy 'TEST_STRING_JSON' from the following function call
//      to the string 'input' in the function declaration
//      and run a test on 'input' to not (!) modify 'TEST_STRING_JSON'
//      but its copy instead

        run_json_test(TEST_STRING_JSON);
    }
}
```
