Stop Writing Clean Code. Start Writing Clear Code

The ratio of time spent reading versus writing code reaches 7 to 1. Unreadable code is technical debt that slows your team down and increases the cost of development in the long run.

Meaningful Variable and Function Names

A name should reveal intent. Variables like d or list1 force you to search through the code, whereas elapsedTimeInDays or activeUsers are self-explanatory. The goal is to make code read like prose.

Single Responsibility Principle (SRP)

A function should do one thing and do it well. A function called handleUserData that fetches data, validates it, saves it to the database, and sends an email is an anti-pattern. Splitting it into validateForm, saveUserToDatabase, and sendWelcomeEmail improves testability and reusability.

Consistent Code Style

Inconsistent style creates visual noise. Linters and formatters like ESLint and Prettier solve this problem automatically.

Modern Approaches to Code Review

Review Checklists:

• Logic: Does it solve the problem? Are edge cases handled?
• Readability: Are names clear? Is the structure overly complex?
• Architecture: Are project patterns respected?
• Tests: Are there tests? Is scenario coverage adequate?

Automated Checks: SonarQube and CodeClimate are CI/CD tools that catch 90% of common issues before human review.

Focus on Learning: Instead of saying "Redo this," try: "What if we tried this approach?" Code review becomes a collaborative effort, not a stressful gatekeeping exercise.

Patterns and Anti-Patterns

Arrow Code (Deep Nesting)

A pyramid of indentation makes code hard to follow:

if (cat wants to play) {
  if (he is in the living room) {
    if (there is a blanket on the sofa) {
      // Logic
    }
  }
}

Guard Clauses (Early Return)

Check negative scenarios and exit early:

if (cat does NOT want to play) { return }
if (he is NOT in the living room) { return }
// Main logic

Magic Numbers

if (cat_state === 1) { pet() }

What does 1 mean? Nobody knows.

Named Constants

const STATE_PURRING = 1;
if (cat_state === STATE_PURRING) { pet() }

Copy-Paste (DRY Violation)

Duplicating logic for two cats:

put_in_bowl("Barsik", "food");
put_in_bowl("Murzik", "food");

Function Instead of Copy-Paste

function feed_cat(cat_name) {
  put_in_bowl(cat_name, "food");
}
feed_cat("Barsik");
feed_cat("Murzik");

Readable Code and Documentation

Good code strives to be self-documenting. Comments should explain why, not what. Tools like JSDoc, Sphinx, and Swagger/OpenAPI generate documentation directly from code.

Practical Tips

• Regular mini-refactorings — improve code incrementally
• Pair programming — code review in real time
• Internal style guides — unified standards across the team

Conclusion: Pragmatism Above All

Clean code is not a silver bullet. For throwaway scripts or prototypes, it's not worth spending hours on architecture. Context decides everything. The goal is to write maintainable code where it truly matters.
