Refactoring

Refactoring is the process of changing existing code to make it easier to understand and modify without change the meaning

It is difficult and dangerous to modify code without unit tests

When you find code that stinks, change it

Or just write it better to begin with: This is about code design, which code is more understandable and maintainable.

Two examples

Consider two more refactorings from suggested readings (see Martin Fowler's Refactoring Catalog)

	Hide Method
	Replace Nested Conditional with Guard Clauses

Remember to read the ones above for Thursday's quiz
