# The MongoDB\BSON\Javascript class

(mongodb >=1.0.0)

## はじめに

BSON type for Javascript code. An optional scope document may be specified that maps identifiers to values and defines the scope in which the code should be evaluated by the server.

> 注意: This BSON type is mainly used when executing database commands that take a Javascript function as a parameter, such as » mapReduce.
