**Description of the problem** The "Adding Control Pages" section includes some details on [how to add javascript](https://docs.expressionengine.com/latest/development/modules.html#javascript) These details include references to `output` and `compile` methods. The `output` method is missing from the documentation of the [javascript class](https://docs.expressionengine.com/latest/development/legacy/libraries/javascript.html#class-reference) that it is presumably part of.
