Property Getters and Setters
Important changes for the Tableau JavaScript API
As of February 2024, the Tableau JavaScript API is deprecated. Use the Embedding API v3 instead for embedding interactive views into web pages and applications. For guidance on embedding Tableau views, see the Tableau Embedding API v3 Help(Link opens in a new window).
Getters and setters are always functions that start with get or set. They can be called multiple times with little performance impact (in other words, they should simply return cached fields or do very simple calculations). Properties are always synchronous and return immediately with the value, rather than having a callback function.
