Refactoring is the process of restructuring existing computer code without changing its external behavior. Its purpose is to improve the nonfunctional attributes of the software, such as readability, complexity, maintainability, and performance, making the code easier to understand and less error-prone.
What are common techniques used in refactoring?
Common techniques used in refactoring include code cleaning, simplifying complex logic, improving naming conventions, modularizing code, and eliminating redundancy.
Why is refactoring important in software development?
Refactoring is important in software development because it helps improve code quality, reduces technical debt, makes the code easier to understand and maintain, and helps prevent bugs by making the codebase more robust.
What are the challenges of refactoring?
Challenges of refactoring include the risk of introducing new bugs, the need for thorough testing, the time and effort required to refactor existing code, and the potential resistance from stakeholders who may not see immediate benefits.
