What is refactoring?

Refactoring involves restructuring existing code to make it cleaner and more efficient. This can include renaming variables, breaking large functions into smaller ones, or removing duplicate code.

The goal of refactoring is to enhance code readability and maintainability, making it easier for developers to understand and work with. It often leads to fewer bugs and a more organized codebase.

For example, if you have a long function that performs multiple tasks, you might refactor it into several smaller functions, each handling a specific task. This makes the code easier to read and test.
