# BSON::Code(3pm)

BSON type wrapper for Javascript code

## NAME

BSON::Code - BSON type wrapper for Javascript code

## VERSION

version v1.12.2

## SYNOPSIS

```
    use BSON::Types ':all';
    $code = bson_code( $javascript );
    $code = bson_code( $javascript, $scope );
```

## DESCRIPTION

This module provides a BSON type wrapper for the "Javascript code" type  and the "Javascript with Scope" BSON types.

## ATTRIBUTES

### code

A string containing Javascript code. Defaults to the empty string.

### scope

An optional hash reference containing variables in the scope of `"code"`. Defaults to `"undef"`.

## METHODS

### length

Returns the length of the `"code"` attribute.

### TO\_JSON

If the `"BSON_EXTJSON"` option is true, returns a hashref compatible with MongoDB's extended JSON \<https://github.com/mongodb/specifications/blob/master/source/extended-json.rst\> format, which represents it as a document as follows:

```
    {"$code" : "<code>"}
    {"$code" : "<code>", "$scope" : { ... } }
```

If the `"BSON_EXTJSON"` option is false, an error is thrown, as this value can't otherwise be represented in JSON.
