Principle 1: Meaningful Naming — Say What You Mean

One of the simplest yet most powerful clean code practices is using meaningful names. Your variables, functions, and file names should explain what they do—without needing comments.

Naming Conventions That Improve Readability

- Use descriptive names (getUserProfile() instead of getData())
- Avoid vague terms like temp, data, info
- Use camelCase for variables and functions in JavaScript
- Be consistent across your codebase

Real-World Examples of Clear vs. Confusing Names

Bad:

let x = getInfo();

Good:

let userProfile = getUserProfile();

Quick Tips for Better Variable and Function Names

- Keep names short but clear
- Use verbs for functions (e.g., fetchData, updateProfile)
- Use nouns for variables and objects

Principle 2: Keep It Simple — Less is Powerful

Complex code might look impressive, but simple code wins every time. A good developer breaks problems into smaller, reusable parts and avoids over-complicating logic.

The Power of Simplicity in Web Development

Simple code is easier to test, debug, and scale. It also helps onboard new developers quickly because the logic is straightforward and understandable.

Avoiding Over-Engineering & Writing Minimal Logic

Don't write code for future scenarios that don't exist yet. Solve the problem at hand with clean logic. Over-engineering adds unnecessary layers and slows down development.

When and How to Refactor for Simplicity

Refactor when:

A function grows beyond 25–30 lines

You find repeated logic (use a helper function)

You see deeply nested if/else or loops (break them up)

Principle 3: Consistent Formatting — Make It Easy on the Eyes

Even the best code can look messy if it’s not formatted properly. Clean formatting makes your code pleasant to read, debug, and collaborate on.

How Formatting Affects Collaboration & Debugging

Messy code slows down teams. Poor spacing, inconsistent indentation, and mixed styles confuse others and waste time during reviews or bug fixes.

Best Practices for Indentation, Spacing & Line Breaks

- Use 2 or 4 spaces consistently (never mix tabs and spaces)
- Add blank lines between logical sections of code
- Break long lines for better readability
- Keep related code blocks together

Using Prettier, ESLint & Other Tools for Automation

Automate formatting using tools like:

Prettier (auto-formats your code consistently)

ESLint (flags code style and logic issues)

EditorConfig (syncs formatting rules across different editors)
