Clean code isn't about perfection—it's about communication. Your code should tell a story that other developers (including your future self) can understand.
Naming Matters
Choose names that reveal intent. A variable named d tells you nothing, but daysSinceLastModification tells you everything.
Functions Should Do One Thing
If you can't describe what your function does without using the word "and," it's probably doing too much.
// Bad
function processUserDataAndSendEmail(user) { ... }
// Better
function processUserData(user) { ... }
function sendWelcomeEmail(user) { ... }
Comments Are Not Always Good
The best code is self-documenting. If you need a comment to explain what code does, consider rewriting the code to be clearer instead.
What?
