Functional code, such as R and Python packages, designed specifically to help users implement common workflows with your data, can be incredibly useful for software developers. These packages provide pre-written code that can be easily integrated into new projects, allowing developers to focus on building new features rather than re-writing code that already exists. In addition, using pre-existing code can help to ensure that new projects are reliable and well-tested, since the packages they rely on have already been used by many other developers. By leveraging existing code in this way, developers can save time and effort while still producing high-quality software for their users.
