How to Improve your Code With easy Refactorings
Refactorings are amazing to grow and improve our code
Refactorings are amazing to grow and improve our code
TL;DR: Let’s start addressing our code smells
I have been writing a series on Code Smells for a long time.
There are a lot of (possible) problems
Let's go for the solutions!
Refactoring 002 - Extract Method
Refactoring 003 - Extract Constant
Refactoring 004 - Remove Unhandled Exceptions
Refactoring 005 - Replace Comment with Function Name
Refactoring 006 - Rename Result Variables
Refactoring 007 - Extract Class
Refactoring 008 - Convert Variables to Constant
Refactoring 009 - Protect Public Attributes
Refactoring 010 - Extract Method Object
Refactoring 011 - Replace Comments with Tests
Refactoring 012 - Reify Associative Arrays
TL;DR: Convert your key/value into full behavioral objects
Refactoring 015 - Remove NULL
TL;DR: Use the Null Object Pattern to eliminate null checks and simplify your code.
Refactoring 016 - Build With The Essence
TL;DR: Pass essential attributes during object creation to reduce mutability and eliminate getters and setters.
Refactoring 017 - Convert Attributes to Sets
TL;DR: Using sets for attributes simplifies your code and makes state management easier
Refactoring 020 - Transform Static Functions
TL;DR: Replace static functions with object interactions.
Refactoring 021 - Remove Dead Code
TL;DR: Eliminate unused functions, constants, and "just-in-case" code.

TL;DR: Extract a common abstract class to mimic real-world structure.
Refactoring 023 - Replace Inheritance with Delegation
TL;DR: Replace restrictive inheritance hierarchies with flexible object delegation
Refactoring 024 - Replace Global Variables with Dependency Injection
TL;DR: Replace global variables with dependency injection to improve testability and reduce coupling. 💉
Refactoring 025 - Decompose Regular Expressions
TL;DR: You can break down a complex validation regex into smaller parts to test each part individually and report accurate errors.
Refactoring 026 - Migrate Global Console Input to Declarative Function
TL;DR: Extract input logic into separate functions to make your code testable, with regressions and more maintainable.
Refactoring 027 - Remove Getters
Refactoring 028 - Replace Consecutive IDs with Dark Keys
