Why does clean code matters so much? Clean code is critical in the software industry as it is often perceived as what makes or breaks a project and it is also what kills a lot of startups and companies because of the exponential growth of technical debt. “He who has a why to live for can bear almost any how.” is a very well known quote written by Friedrich Nietzche in his book Twilight of the Idols. When people have their own habit of coding or of anything, it is very hard to change them. The best way is to make them want to change by showing them that it is in their best interest to do so. This is the reason why I’m starting this article with an explanation on why we need cleaner code in our application by dismantling a few misconceptions most of us have regarding our work as software developers.

1. The Importance of
Clean Code
Eric Jeker

2. “He who has a why to live for can bear
almost any how.”

3. You spend most of your time
reading code…

4. Code feeds
itself with
your time
Every line of code introduces
■ Bugs
■ Breaking changes
■ Need for tests

5. The more code,
the more complexity

6. …the more complexity,
the more expensive.

7. Shit Rolls Downhill

8. Time heals everything…
… except bad code

9. Your craft is to write
efficient code

10. What is

■ Readable
■ Isolated scope
■ Testable

11. “Any fool can write code that a computer can
understand. Good programmers write code that
humans can understand.”
- Martin Fowler

12. How to write
clean code?

13. “Always code as if the guy who

- Martin Golding

14. Stop ignoring
the clichés!
● DRY
● KISS
● YAGNI
● SOLID
● MVC
● Design Patterns
● Coding Standards/Conventions
● RASAP (Don’t clog the shit pipe!)
● “Don’t reinvent the wheel”
and many more...

15. Create small, repeatable
mind patterns

16. Trust
your gut
STOP!
Think, Refine

17. Know your
tools
● A few languages
● A few frameworks
● A few tools
Master...

18. Coding is not about
production, it’s about
craftsmanship.

19. ■ Bad code is going to cost you a lot in the long run
■ Don’t be the one who clog the shit pipe
■ Keep it simple and readable by others
