📌 Why does clean code matter?

Code is written once but read dozens of times. As Robert Martin says in his famous book "Clean Code", we spend ten times longer reading code than writing it. So write your code for the person who will read it in the future — most often, that's you six months from now.

5 practical rules 💡

First — pay attention to naming: a variable name should say what it holds, a function name should say what it does. Write "activeUsers" or "totalPrice", not "data" or "temp".

Second — keep functions small: one function, one job. Third — avoid repetition (DRY): if the same code appears in two places, extract it into a function. Fourth — write comments only for things the code itself cannot say. Fifth — refactor continuously: even working code can be improved.

Conclusion 🚀

Clean code is not a talent — it's a habit. Even the habit of re-reading your code once before submitting it noticeably raises the quality. Start small: review the names of the functions you wrote today.
