Overview
YAGNI is a warning against 'speculative generality.' Developers often add features they think they might need in the future, which leads to wasted effort and increased complexity.
Why YAGNI?
- Wasted Time: Building features that are never used.
- Increased Maintenance: Every line of code must be maintained and tested.
- Obscured Logic: Extra code makes the core logic harder to follow.
Rule of Thumb
Only implement what you need for the current requirements. If you need it later, you can add it then.
