Clean Code Tip 7: Keep it simple, stupid (KISS)
KISS is a design principle that suggests systems work best when they are simple, not complicated. The word “stupid” is not meant to insult anyone, even if it might sound that way. It serves as a clear reminder to avoid overthinking or making things more difficult than necessary.
Why does KISS matter for clean code? Clean code should be easy to read. When code gets too complicated, it becomes harder to understand and also more difficult to update.
It is advisable to begin with a simple solution and assess its adequacy before introducing additional complexity. Complexity should be added only when necessary. For example, premature optimization should be avoided; optimization efforts should be undertaken only after performance has been measured and a clear justification exists. Typically, optimizations introduce additional complexity to otherwise straightforward solutions.
