JavaScript Fundamentals

Beginner

JavaScript is the programming language of the web. Learn how to add interactivity to your websites and build web applications.

1 Variables and Data Types

Learn how to declare variables and work with different data types in JavaScript.

let name = "Alice";
const age = 30;
var isStudent = true;

2 Functions

Functions are reusable blocks of code that perform specific tasks.

function greet(name) {
    return `Hello, ${name}!`;
}

const greetArrow = (name) => `Hello, ${name}!`;
JavaScript Tutorial

DOM Manipulation

Intermediate

Learn how to interact with the Document Object Model (DOM) to create dynamic web pages.

1 Selecting Elements

Use JavaScript to select and manipulate HTML elements.

const button = document.getElementById('myButton');
const elements = document.querySelectorAll('.items');

2 Event Listeners

Respond to user interactions like clicks and key presses.

button.addEventListener('click', () => {
    console.log('Button clicked!');
});
DOM Manipulation

Python Basics

Beginner

Python is a versatile language used for web development, data analysis, AI, and more.

1 Variables and Data Types

Learn Python's simple and readable syntax for working with data.

name = "Alice"
age = 30
is_student = True

2 Functions

Define reusable blocks of code with Python functions.

def greet(name):
    return f"Hello, {name}!"

greet_lambda = lambda name: f"Hello, {name}!"
Python Tutorial

Lua Game Scripting

Intermediate

Lua is a lightweight scripting language often used in game development.

1 Basic Syntax

Learn Lua's simple and flexible syntax.

local name = "Alice"
local age = 30
local isStudent = true

2 Tables

Tables are Lua's primary data structure, serving as arrays and dictionaries.

local player = {
    name = "Hero",
    health = 100,
    inventory = {"sword", "potion"}
}
Lua Tutorial

C# Fundamentals

Beginner

C# is a powerful language for building Windows applications and games with Unity.

1 Variables and Types

C# is a statically-typed language with strong type checking.

string name = "Alice";
int age = 30;
bool isStudent = true;

2 Classes and Objects

C# is an object-oriented language with classes and inheritance.

public class Person {
    public string Name { get; set; }
    public int Age { get; set; }
    
    public Person(string name, int age) {
        Name = name;
        Age = age;
    }
}
C# Tutorial

C++ Basics

Advanced

C++ is a high-performance language used for system/software development and game engines.

1 Variables and Pointers

C++ gives you low-level memory access through pointers.

int age = 30;
int* agePtr = &age;
cout << *agePtr; // Output: 30

2 Classes and Objects

C++ supports object-oriented programming with classes.

class Rectangle {
private:
    int width, height;
public:
    Rectangle(int w, int h) : width(w), height(h) {}
    int area() { return width * height; }
};
