Refaktoreringen

Refaktoreringen, or refactoring in English, is the process of restructuring existing computer code without changing its external behavior. The primary goal of refactoring is to improve the internal structure of the code, making it more readable, understandable, and maintainable. This can involve various techniques such as extracting methods, renaming variables, simplifying conditional logic, and removing duplicate code.

Refactoring is an essential practice in agile software development. It allows developers to continuously improve the codebase as new features are added or requirements change. By addressing technical debt early and often, refactoring helps prevent the accumulation of poorly structured code that can become increasingly difficult and costly to modify over time. This leads to a more robust and adaptable system, reducing the risk of introducing bugs during future development.

While refactoring does not add new functionality, it can uncover hidden bugs or design flaws in the existing code. It is typically performed in small, incremental steps, with comprehensive testing after each step to ensure that the external behavior of the software remains unchanged. This disciplined approach minimizes the risk of introducing regressions. The benefits of refactoring include increased developer productivity, improved code quality, and a more stable and sustainable software product.
