What are the advantages of refactoring code?

Code refactoring is the process of improving the internal structure of a software code without changing its external behavior. The main advantages of refactoring:

• Improved readability: the code becomes easier to understand and maintain.
• Enhanced support and extensibility: easier to make changes and add new features.
• Reduced errors: simplifying logic helps avoid bugs.
• Performance optimization: sometimes refactoring helps make the code more efficient.

Example of simple refactoring in Python:

# Was
if status == 1:
    print("Active")
else:
    print("Inactive")

# Now
status_messages = {1: "Active", 0: "Inactive"}
print(status_messages.get(status, "Unknown"))

This approach makes the code more compact and understandable.
