What Is Quality and How Does It Relate to Refactoring?
There have been countless efforts to determine what makes for quality code. Some are determined by collections of principles:
- SOLID: Single responsibility, open/closed, Liskov substitution, interface segregation, and dependency inversion
- DRY: Don’t repeat yourself
- KISS: Keep it simple, stupid
- GRASP: General responsibility assignment software patterns
- YAGNI: Ya ain’t gonna need it
Flowing from that, our tactical concerns are to write tests for code, and write code that is easily testable. Here I not so humbly introduce the EVAN principles of code quality:
- Extract functions and modules to simplify interfaces
- Verify code behavior through tests
- Avoid impure functions when possible
- Name variables and functions well
What Is and Isn’t Refactoring
Before we leave off, let’s once again distinguish between refactoring and other lookalike processes. Here is a list of things that are not refactoring. Instead, they create new code and features:
- Adding square root functionality to a calculator application
- Creating an app/program from scratch
- Rebuilding an existing app/program in a new framework
- Adding a new package to an application or program
- Addressing a user by first and last name instead of first name
- Localizing
- Optimizing performance
- Converting code to use a different interface (e.g., synchronous to asynchronous or callbacks to promises)
