The Art of Clean Code

Writing code that works is easy. Writing code that's a pleasure to read is an art form.

Why Clean Code Matters

• Maintainability - Clean code is easier to modify
• Collaboration - Your team will thank you
• Mental health - No one likes wading through a mess

Principles

Readability First

Code is read far more often than it's written. Optimize for the reader, not the writer.

// Good
function calculateUserAge(birthDate: Date): number {
  const today = new Date();
  const age = today.getFullYear() - birthDate.getFullYear();
  return age;
}

// Bad
function calc(d: Date): number {
  return new Date().getFullYear() - d.getFullYear();
}

Consistency

Pick a style and stick with it. Consistency beats "correctness" every time.

Delete Code

Don't comment out code. Delete it. That's what version control is for.

Final Thoughts

Clean code isn't about following rules dogmatically. It's about respect: for your future self, for your teammates, and for the craft of programming itself.
