Book notes – Refactoring: Improving the Design of Existing Code – Chapter 2

Refactoring helps you develop code more quickly

Refactoring is something you do all the time in little bursts. You don’t decide to refactor, you refactor because you want to do something else, and refactoring helps you do that other thing.

The Rule of Three

Refactor when you add a function/feature
Whenever I have to think to understand what the code is doing, I ask myself if I can refactor the code to make that understanding more immediately apparent.

But on the next step you will be almost Refactoring without doing a conscious exercise.
