Clean Code
The classic guide to writing code humans can read — clear names, small functions and maintainable structure.
Code is for humans
The core idea: code is read far more than it is written, so time spent improving readability pays back many times over in maintenance.
Meaningful names
Don't abbreviate until ambiguity becomes the rule. A good name tells you what it does without a comment.
Small functions
A function should do one thing and operate at one level of abstraction. Smaller and clearer functions are easier to test.
Comments come last
Don't comment bad code — rewrite it. Good comments explain why, not what.
Testing and refactoring
The book covers automated tests as a safety net that enables improvement, plus the discipline of teamwork.
🔑 Key actionable ideas

- Clear names beat comments.
- Small, single-purpose functions are easier to maintain.
- Don't comment bad code; rewrite it.
