Software is a living system. A codebase will grow, require updates, and eventually be passed on to other developers. Writing clean, documented code is not just a best practice—it's an investment in your company's future. It keeps maintenance costs low and features delivery high.
Self-Documenting Code
We avoid cryptic abbreviations. A variable named activeUserAccountCount is infinitely better than actUsrCt. Code should read like structured English. Good naming conventions reduce the cognitive load needed to understand what a function does. Comments should explain the *why*, not the *what*.
Single Responsibility
Every function, component, or class should do one thing and do it well. If a function is validating input, saving it to a database, and sending an email, it should be broken down into three specialized helper functions. This makes code modular, easy to test, and simple to debug. It prevents regressions when refactoring sections.
