What programming language is used to create add-ons through Google Apps Script?

Google Apps Script utilizes JavaScript as its programming language for creating add-ons. JavaScript is a versatile, high-level language that is particularly well-suited for manipulating web applications, which is central to the functions of Google Workspace applications like Google Docs, Sheets, and Slides.

Apps Script is designed to extend and enhance the capabilities of these applications through custom functions, menus, and user interfaces, all of which can be seamlessly integrated with existing Google services. The use of JavaScript allows developers to easily connect their scripts with web APIs and incorporate dynamic features, enhancing user interaction within the apps.

Other programming languages mentioned like Java, C++, and Python do not have direct support for Google Apps Script. While they are powerful languages in their own right, they are not the platforms through which Google Apps Script operates, making JavaScript the exclusive choice for this environment.
