Zaraz Context
The Zaraz Context is a versatile object that provides a set of configurable properties for Zaraz, a web analytics tool for tracking user behavior on websites. These properties can be accessed and utilized across various components, including Worker Variables and JSONata expressions.
System properties, which are automatically collected by Zaraz, provide insights into the user’s environment and device, while Client properties, obtained through Zaraz Web API calls like zaraz.track(), offer additional information on user behavior and actions.
