## When to Refactor
Strategies during construction:
1. Extend and then refactor
1. Refactor to extend
1. Debug and then refactor
1. Refactor to debug
1. Refactor to understand
----
### Extend and then refactor
When you need to add a new functionality:
- Find a class or method with similar behavior and copy it
- Make it work
- Eliminate redundancy
----
### Refactor to extend
- A functionality seems too complex to implement
- Refactor the current design to make the change easy
- Make the change
----
### Debug and then refactor
- Locate and fix the bug
- Refactor tge code to make the bug obvious:
- Add assertions
- Extract method
- Assign meaningful names
- Create explaining constants for magic numbers
- Create explaining constants or variables for complex expressions
----
### Refactor to debug
- Since refactor operations are behavior-preserving, they also preserve bad behavior.
- Before debugging, refactor to simplify complex code
- Then, debug it
----
### Refactor to understand
- Refactor when trying to understand a complex code:
- Split large methods
- Create explaining constants or variables for magic numbers
- Assign meaningful names
- Do not worry about performance

#### Comments
#### Comments
- A comment should describe an intention and not explain an action.
- Too many unnecessary comments overloads the code and make it unreadable.
