The Art of Writing Clean Code

Code is Communication

Your code communicates with future developers—including future you. Make it clear.

Naming Things

Use descriptive names. getUserById is better than getData.

Functions Should Do One Thing

Small, focused functions are easier to test, debug, and reuse.

Comments Explain Why, Not What

Good code is self-documenting. Comments should explain decisions and reasoning.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand. — Martin Fowler
