Refactoring is the process of improving code structure without changing its external behavior. Here are common techniques:

1. Rename Variable/Method

Replace unclear names with meaningful ones.

Rename_Variable

2. Extract Method

Break down large functions into smaller, reusable ones.

3. Remove Duplicate Code

Eliminate redundant code blocks through abstraction.

4. Inline Method

Replace a method with its implementation if it's only used once.
