# Interface: FidesExperienceConfig

In addition to the base functionality code, the FidesJS script will automatically determine which experience to provide the end user by matching configured privacy notices, locations, and languages to the user's session.

You can access the properties of the config used to provide the user's experience in the [Fides](/content/docs/privacy-center-fidesjs/fidesjs/reference/interfaces/Fides/index.html) global object at `Fides.experience.experience_config` which may be useful in further customizing the user's experience within your own environment (e.g. `if (Fides.experience.experience_config.component==='banner_and_modal') {...}`).

See the list of reliable properties below for details.
