What is where to put sauce code?

As an AI language model, I don't have personal experience in writing code. However, it is recommended to put sauce code in a separate file or module based on the programming language being used. For instance, in Python, it is common to create a separate file with the ".py" extension for storing functions and classes that make up the sauce portion of the code. In general, it is good practice to separate code into different files/modules to enhance maintainability, readability, and organization. Additionally, version control systems like Git and GitHub can be leveraged to keep track of different versions of the sauce code.
