How do you organize your code? Do you use the module pattern or inheritance?

I organize code following SOLID, DRY, and KISS principles. I use a component-based approach, grouping related logic, markup, and styles.

I apply naming conventions (e.g., BEM for CSS) for clarity and maintainability.

I actively use module patterns with ES Modules (import/export) to split code into independent, reusable parts. This helps manage dependencies, avoid naming conflicts, and facilitates testing.

I prefer composition over inheritance, as it offers greater flexibility and avoids the "diamond inheritance" problem. Inheritance can be useful for creating base classes with common functionality, but for most logic, I pass functionality via properties or function arguments.

I use build tools (Webpack, Vite) for transpilation (Babel), minification, bundling, and resource loading optimization. I utilize linters (ESLint) and formatters (Prettier) to maintain a consistent code style and catch errors early.

Example of module organization:

// src/components/Button/Button.js
import React from 'react';
import './Button.css';

const Button = ({ children, onClick }) => {
  return (
    <button className="button" onClick={onClick}>
      {children}
    </button>
  );
};

export default Button;

Comparison table of modules and inheritance:

Feature	Modules (ES Modules)	Inheritance (Classes)
Reusability	High	Medium (via base classes)
Flexibility	High (composition)	Medium (rigid definition)
Dependencies	Explicit (import/export)	Implicit (class hierarchy)
Testing	Easier	Can be more complex
Name collisions	Absent (isolation)	Can occur
