Clean Code Essentials: YAGNI, KISS, DRY

The article presents YAGNI, KISS, and DRY as principles that support effective software development. It says YAGNI helps avoid unnecessary complexity by delaying features until they are needed, KISS favors straightforward solutions, and DRY reduces repetition by keeping a single source of truth.

• YAGNI recommends implementing features only when they are actually needed, so the code stays simple and avoids over-engineering.
• KISS encourages the simplest solution that meets the requirements, which makes code easier to read, debug, extend, and maintain.
• DRY says repeated code or logic should be consolidated into reusable functions, classes, or modules to reduce errors and inconsistencies.
• The article links these three principles to cleaner, more maintainable code and a more efficient development process.
• It also says these principles make software easier to understand, modify, and extend, and mentions SOLID as the next topic.
