class Car:
    def __init__(self, make, model, year):
        self.make = make
        self.model = model
        self.year = year
        self.speed = 0

    def accelerate(self, increment):
        self.speed += increment

    def brake(self, decrement):
        self.speed = max(0, self.speed - decrement)

    def get_info(self):
        return f"{self.year} {self.make} {self.model}, current speed: {self.speed} mph"

# Creating an instance of the Car class
my_car = Car("Toyota", "Corolla", 2022)
my_car.accelerate(30)
print(my_car.get_info())  # Output: 2022 Toyota Corolla, current speed: 30 mph

This example demonstrates key OOP concepts such as classes, objects, methods, and encapsulation. Understanding these paradigms will help you write more organized, maintainable code and choose the right approach for different projects.

3. Version Control

Version control is a fundamental skill that every developer, self-taught or otherwise, must master. Git is the most widely used version control system, and understanding its concepts and commands is crucial for collaborating with other developers and managing your own projects.

Key Git concepts to learn include:

  • Basic commands (init, add, commit, push, pull)
  • Branching and merging
  • Resolving conflicts
  • Working with remote repositories
  • Git workflows (e.g., Git Flow, GitHub Flow)

Here’s a basic example of using Git commands:

# Initialize a new Git repository
git init

# Add files to the staging area
git add .

# Commit changes
git commit -m "Initial commit"

# Create and switch to a new branch
git checkout -b feature-branch

# Make changes and commit
git add .
git commit -m "Add new feature"

# Switch back to the main branch
git checkout main

# Merge the feature branch
git merge feature-branch

# Push changes to a remote repository
git push origin main

Mastering version control will not only help you manage your own projects more effectively but also prepare you for collaborative work environments.

4. Database Fundamentals

While not all developers work directly with databases, understanding database concepts is crucial for building robust applications. Whether you’re working with relational databases like MySQL or PostgreSQL, or NoSQL databases like MongoDB, grasping the fundamentals will serve you well.

  • Database design and normalization
  • Indexing and query optimization
  • Transactions and ACID properties

Here’s a simple example of a SQL query:

-- Create a table
CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) UNIQUE,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- Insert data
INSERT INTO users (id, username, email) VALUES (1, 'johndoe', 'john@example.com');

-- Query data
SELECT * FROM users WHERE username = 'johndoe';

Understanding database fundamentals will help you design more efficient data models and write optimized queries, skills that are valuable in many development roles.

5. Web Technologies and Protocols

For many self-taught developers, web development is often the entry point into programming. However, it’s crucial to understand the underlying technologies and protocols that power the web, rather than just focusing on specific frameworks or libraries.

Key web fundamentals to master include:

  • HTML, CSS, and JavaScript
  • HTTP/HTTPS protocols

  • Web security basics (CORS, XSS, CSRF)
  • Browser rendering and the Document Object Model (DOM)
  • Responsive design principles

Here’s a simple example of a RESTful API endpoint using Express.js:

const express = require('express');
const app = express();

app.get('/api/users', (req, res) => {
  // In a real application, this data would come from a database
  const users = [
    { id: 1, name: 'John Doe' },
    { id: 2, name: 'Jane Smith' }
  ];
  res.json(users);
});

app.listen(3000, () => {
  console.log('Server running on port 3000');
});

Understanding these fundamentals will give you a deeper appreciation of how web applications work and help you build more robust, scalable web solutions.
