Code Layout Examples

Here are several common code layout patterns across different programming languages:

1. Modular Design (Python)

# utils.py
def helper_function():
    """Example of a utility function"""
    return "Helper output"

# main.py
import utils

def main():
    result = utils.helper_function()
    print(result)

if __name__ == "__main__":
    main()

2. Fluent Interface (JavaScript)

// config.js
const config = {
    setOption(option, value) {
        this[option] = value;
        return this;
    }
};

// usage.js
config.setOption('timeout', 5000)
      .setOption('debug', true)
      .setOption('port', 3000);

3. Clean Code Principles (Java)

// Service.java
public class UserService {
    private UserRepository userRepo;

    public UserService(UserRepository repo) {
        this.userRepo = repo;
    }

    public void registerUser(User user) {
        if (user.isValid()) {
            userRepo.save(user);
        }
    }
}
