Clean Code Principles

Martin Fowler famously said, 'Any fool can write code that a computer can understand. Good programmers write code that humans can understand.' Clean code is not about clever one-liners; it's about clarity.

Meaningful Names

Variables should reveal intent. `d` is bad. `daysSinceCreation` is good. You should be able to read your code like a book.

Functions Should Do One Thing

The Single Responsibility Principle applies to functions too. If your function is doing 'A' and 'B', split it into two functions. This makes testing and debugging exponentially easier.

Formatting

Consistent indentation and spacing are vital. Use a linter or a Code Editor with auto-formatting to enforce these rules automatically.

Conclusion

Clean code is a habit. It takes more time upfront but saves massive amounts of time during maintenance.
