What programming language is used in Tableau?

The question is about Tableau

Answer:

Tableau uses a proprietary language called VizQL, or Visual Query Language, to translate user actions into database queries and create visualizations. It also integrates SQL to query databases, MDX or Multidimensional Expressions, and DAX or Data Analysis Expressions to handle OLAP data in Tableau. The calculation fields within Tableau can let the user define custom calculations through formula languages similar to SQL functions. While Tableau itself is written in C++ core functionality with Java on top for some components, the API work does extend functions and automate tasks or integrate into other applications in Python, R, and JavaScript as well.
