Refactoring

What is meant by Refactoring?

In software development, refactoring refers to the process of restructuring existing source code without changing its external functionality. The goal is to improve the internal structure, readability, maintainability, and extensibility of the code while preserving its original functionality.

Typical software functions in the area of "Refactoring":

1. Code Analysis: Automatic detection of code smells and improvement potentials.
2. Automated Restructuring: Performing common refactoring operations such as renaming or extracting methods.
3. Preview Function: Displaying the effects of a refactoring before actual implementation.
4. Version Control Integration: Tracking changes and easily undoing refactorings.
5. Test Automation: Executing unit tests after each refactoring to ensure functionality.
6. Performance Analysis: Measuring the impact of refactorings on code performance.

Examples of "Refactoring":

1. Method Extraction: Moving a code segment into a separate method to improve readability.
2. Renaming: Changing variable or method names to increase comprehensibility.
3. Remove Duplication: Merging redundant code into a common method.
4. Interface Extraction: Creating an interface from a class to improve modularity.
5. Restructure Inheritance Hierarchy: Adjusting the class structure to optimize code organization.
6. Simplify Conditions: Reformulating complex logical expressions to increase readability.
