# <small>nlohmann::json_pointer::</small>operator/

```cpp
// (1)
json_pointer operator/(const json_pointer& lhs, const json_pointer& rhs);

// (2)
json_pointer operator/(const json_pointer& lhs, string_t token);

// (3)
json_pointer operator/(const json_pointer& lhs, std::size_t array_idx);
```

1. create a new JSON pointer by appending the right JSON pointer at the end of the left JSON pointer
2. create a new JSON pointer by appending the unescaped token at the end of the JSON pointer
3. create a new JSON pointer by appending the array-index-token at the end of the JSON pointer

## Parameters

`lhs` (in)
:    JSON pointer

`rhs` (in)
:    JSON pointer to append

`token` (in)
:    reference token to append

`array_idx` (in)
:    array index to append

## Return value

1. a new JSON pointer with `rhs` appended to `lhs`
2. a new JSON pointer with unescaped `token` appended to `lhs`
3. a new JSON pointer with `array_idx` appended to `lhs`

## Complexity

1. Linear in the length of `lhs` and `rhs`.
2. Linear in the length of `lhs`.
3. Linear in the length of `lhs`.

## Examples

??? example

    The example shows the usage of `operator/`.
     
    ```cpp
    --8<-- "examples/json_pointer__operator_add_binary.cpp"
    ```
    
    Output:
    
    ```json
    --8<-- "examples/json_pointer__operator_add_binary.output"
    ```
