What is the purpose of commenting code?

Commenting code serves the primary purpose of providing clarity and explanation for functionality. This practice allows developers to describe the intention behind certain sections of the code, making it easier for others (or themselves at a later time) to understand what the code is supposed to achieve. Well-placed comments can elucidate complex logic, outline the purpose of functions, clarify variable usage, and provide context that can be essential during maintenance or debugging.

Good comments enhance the readability of code, which is crucial as projects can grow large and become challenging to navigate. Effective commenting practice is a vital aspect of programming since clear documentation through comments can significantly reduce the time needed for others to familiarize themselves with the codebase, aiding collaboration and future development efforts.
