Refactoring is the process of improving code structure without changing its external behavior. It focuses on making code cleaner, more readable, and easier to maintain. Refactoring includes techniques such as extracting functions, renaming variables, simplifying logic, and breaking large components into smaller pieces.
Why it matters
Refactoring prevents technical debt, reduces bugs, and keeps codebases sustainable over time. It improves collaboration and enables faster feature development. AI tools can assist with refactoring by suggesting simplifications and catching structural issues.
Examples
Extracting repeated logic into a helper function or reorganizing modules for clarity. Lessons like Refactoring With AI show how AI assists in the process.
