JavaScript Tutorials

    Learn JavaScript from Beginner to Advanced

    Master JavaScript programming with our comprehensive, hands-on tutorials. Each tutorial includes practical examples, exercises, and real code you can run in our online compiler.

    JavaScript Fundamentals
    Beginner

    Master the basics of JavaScript programming • Duration: 2 hours

    What You'll Learn:

    • Variables and Data Types

    • Functions and Scope

    • Control Structures (if/else, loops)

    • Arrays and Objects

    • DOM Manipulation Basics

    Code Example:
    // JavaScript Fundamentals Example
let greeting = "Hello, World!";
const numbers = [1, 2, 3, 4, 5];

function calculateSum(arr) {
  return arr.reduce((sum, num) => sum + num, 0);
}

console.log(greeting);
console.log("Sum:", calculateSum(numbers));
    Modern JavaScript (ES6+)
    Intermediate

    Explore modern JavaScript features and syntax • Duration: 3 hours

    What You'll Learn:

    • Arrow Functions and this binding

    • Destructuring Assignment

    • Template Literals

    • Promises and Async/Await

    • Modules and Classes

    Code Example:
    // Modern JavaScript Example
const users = [
  { name: 'John', age: 30 },
  { name: 'Jane', age: 25 }
];

// Destructuring and arrow functions
const getUserNames = (users) => {
  return users.map(({ name }) => name);
};

// Async/await example
async function fetchUserData(id) {
  try {
    const response = await fetch(`/api/users/${id}`);
    const userData = await response.json();
    return userData;
  } catch (error) {
    console.error('Error:', error);
  }
}

console.log(getUserNames(users));
    JavaScript and the DOM
    Intermediate

    Learn to manipulate web pages with JavaScript • Duration: 2.5 hours

    What You'll Learn:

    • Selecting DOM Elements

    • Event Handling

    • Creating and Modifying Elements

    • Form Validation

    • Local Storage and Session Storage

    Code Example:
    // DOM Manipulation Example
document.addEventListener('DOMContentLoaded', () => {
  const button = document.getElementById('myButton');
  const output = document.getElementById('output');
  
  button.addEventListener('click', (event) => {
    const newElement = document.createElement('p');
    newElement.textContent = 'Button clicked!';
    newElement.style.color = 'green';
    output.appendChild(newElement);
  });
  
  // Form validation example
  const form = document.getElementById('myForm');
  form.addEventListener('submit', (e) => {
    const email = document.getElementById('email').value;
    if (!email.includes('@')) {
      e.preventDefault();
      alert('Please enter a valid email');
    }
  });
});
    Advanced JavaScript Concepts
    Advanced

    Deep dive into advanced JavaScript programming • Duration: 4 hours

    What You'll Learn:

    • Closures and Lexical Scope

    • Prototypes and Inheritance

    • Event Loop and Asynchronous Programming

    • Design Patterns

    • Error Handling and Debugging

    Code Example:
    // Advanced JavaScript Example
// Closure example
function createCounter() {
  let count = 0;
  return function() {
    return ++count;
  };
}

const counter = createCounter();
console.log(counter()); // 1
console.log(counter()); // 2

// Prototype example
function Person(name, age) {
  this.name = name;
  this.age = age;
}

Person.prototype.greet = function() {
  return `Hello, I'm ${this.name} and I'm ${this.age} years old.`;
};

const person1 = new Person('Alice', 30);
console.log(person1.greet());
