Refactor long methods by applying the Extract Method technique to isolate logical units into separate methods, then validate the changes with existing tests to ensure behavior remains unchanged.

Common code smells include long methods, duplicated logic, and complex conditionals. Identifying these smells during code reviews helps target areas for refactoring techniques like Move Method or Extract Class.

Reduce duplicated logic by applying refactoring patterns such as Extract Method or Extract Class to consolidate repeated code blocks, running safety checks and linting to preserve external behavior.

Yes, this refactoring approach targets typical imperative codebases in JavaScript and TypeScript, applying safe incremental changes to improve code quality during maintenance and feature work.

Use Move Method to relocate a function to a more appropriate class, and use Extract Class when a single class has too many responsibilities, isolating distinct features into separate classes.
