Clean Code Matters: Writing Readable Code in Swift, Dart, and JavaScript etc

Clean Code Matters

💡 Writing clean, readable code today saves hours of debugging tomorrow.

Why It Matters

Code is read far more often than it is written. A well-structured, readable codebase helps future developers (including your future self) maintain and scale the project with ease.

Examples of Clean Code

Swift Example (Clean vs Messy)

// ❌ Messy
func g(a: Int, b: Int) -> Int { return a+b }

// ✅ Clean
func addNumbers(_ firstNumber: Int, _ secondNumber: Int) -> Int {
    return firstNumber + secondNumber
}

Dart Example (Clean vs Messy)

// ❌ Messy
void p(n) {
  print(n);
}
// ✅ Clean
void printMessage(String message) {
  print(message);
}

JavaScript Example (Clean vs Messy)

// ❌ Messy
function c(u){return u*2;}

// ✅ Clean
function calculateDouble(userInput) {
  return userInput * 2;
}

Takeaway

✨ Optimize for readability, not just execution. Use clear naming, proper formatting, and avoid shortcuts that make code harder to understand.
