Clean Code

If you want to write clean code, then learn these 6 rules:

Separation of Concerns (SOC)

• Break down a complex program into smaller units.
• Each unit should focus on a specific task.

Document Your Code (DYC)

• Write code for your future self and others.
• Explain complex code sections with comments and documentation.

Don’t Repeat Yourself (DRY)

• Don’t waste time writing the same code again.
• Instead use functions, modules, and existing libraries.

Keep It Simple, Stupid (KISS)

• Simple is hard, but better.
• Readable code > clever code.

Test Driven Development (TDD)

• Write a failing test first.
• Write code to make the test pass.
• Then clean up the code without changing behaviour.

You Ain’t Gonna Need It (YAGNI)

• Build only essential features.
• Don’t build features you think you might need later.

The bottom line: Leave the codebase cleaner than you found it.
