Which programming language is Puppet primarily written in?

Puppet is primarily written in Ruby, which is significant for several reasons. Ruby's flexibility, readability, and strong support for object-oriented programming make it an ideal choice for a configuration management tool like Puppet. The language allows developers to write concise and expressive code, facilitating the automation of system management tasks. Additionally, Ruby has a rich ecosystem of libraries and frameworks that Puppet leverages, enhancing its functionality and extensibility.

While other languages listed in the choices, such as Python, JavaScript, and Go, are popular in various domains, they are not the foundation upon which Puppet is built. Python, for example, is widely used in automation and scripting but is not the main language for Puppet's implementation. Understanding the architecture of Puppet and its reliance on Ruby can provide deeper insights into how the tool operates and can lead to more effective usage and customization.
