# 3.1 Code Refactoring and Formatting

#### Code Refactoring

Code refactoring involves adjusting and optimizing the code structure and organization without altering its functionality. VSCode provides a rich set of code refactoring features, including:

- **Rename symbol**: Rename variables, functions, or classes to more descriptive names.
- **Extract method**: Move code blocks into a new method to improve code readability and maintainability.
- **Inline variable**: Inline variable declarations into their usage positions to eliminate unnecessary variables.
- **Move type**: Move type declarations to more appropriate locations to enhance code r
