"Adding functionality is not just a matter of adding code"

This quote by Wietse Venema is a suggestion that when it concerns software application advancement, just adding code is insufficient. It is very important to consider the overall functionality of the software and how the code will interact with the existing codebase. Adding code without considering the general functionality can result in unanticipated outcomes and can cause the software to become unsteady. It is important to think about the impact of the code on the existing system and how it will interact with other components. Furthermore, it is essential to think about the security ramifications of the code and how it will affect the general security of the system. Including code without considering these aspects can cause serious security vulnerabilities. Eventually, including performance is not just a matter of including code, but rather a mindful factor to consider of the total system and how the code will communicate with the existing codebase.
