إعادة الهيكلة الآمنة باستخدام IDE

في هذا الدرس

change structure without changing behavior.

الموضوعات المخطط لها

• Refactoring: change the code's structure, not what it does.
• Always have tests first, and run them after each step.
• Use IDE tools: Rename, Extract Method, Extract Variable, Move, Inline.
• One small step per commit, named after the refactoring.
• No new features and no bug fixes in the same commit.
