Which programming languages are commonly used with Sitecore XM Cloud?

C# and JavaScript are the primary programming languages used with Sitecore XM Cloud. C# is integral to Sitecore development as the platform itself is built on the .NET framework, making C# essential for creating custom components, templates, and modules within Sitecore. Additionally, JavaScript plays a crucial role in developing the front-end aspects of a Sitecore application, including client-side interactivity, which is important in delivering a responsive user experience.

The combination of C# and JavaScript allows developers to effectively work on both the server-side functionality and the client-side presentation, making this pair particularly suited for the development tasks involved in Sitecore XM Cloud. Other programming languages are not typically associated with Sitecore in the same way, hence they are less relevant to this context.
