JavaScript Essentials Course

What You'll Learn

  • JavaScript fundamentals and core concepts
  • DOM manipulation and event handling
  • Modern ES6+ features (arrow functions, destructuring, etc.)
  • Working with APIs and asynchronous JavaScript
  • Error handling and debugging techniques
  • Building an interactive web application

A Taste of JavaScript

Here's a glimpse of what you'll be learning and creating during the course.

Basic DOM Manipulation

// Select elements
const button = document.querySelector('#myButton');
const output = document.querySelector('#output');

// Add event listener
button.addEventListener('click', () => {
  // Change content
  output.textContent = 'Button was clicked!';

  // Add a class for styling
  output.classList.add('highlight');

  // Create a new element
  const timestamp = document.createElement('div');
  timestamp.textContent = new Date().toLocaleTimeString();

  // Add it to the DOM
  output.appendChild(timestamp);
});

You'll learn how to select elements, listen for events, manipulate content, and dynamically create new elements to create interactive user experiences.

Modern ES6+ Features

// Default parameters
const greet = (name = 'Guest') => `Hello, ${name}!`;

// Destructuring
const person = { name: 'Sofia', age: 28, city: 'Limassol' };
const { name, city } = person;

// Spread operator
const numbers = [1, 2, 3];
const moreNumbers = [...numbers, 4, 5];

// Async/await for API calls
async function fetchUserData(userId) {
  try {
    const response = await fetch(`https://api.example.com/users/${userId}`);
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Error fetching user data:', error);
  }
}

You'll master modern JavaScript features that make your code more concise, readable, and powerful, preparing you for professional development environments.

Frequently Asked Questions

Get answers to common questions about our JavaScript Essentials course.

How much HTML & CSS knowledge do I need?

You should have a basic understanding of HTML and CSS before starting this course. You should be comfortable with:

  • Creating HTML documents with proper structure
  • Using common HTML elements (headings, paragraphs, links, images)
  • Basic CSS styling and selectors
  • Understanding the box model and simple layouts

Our HTML & CSS Fundamentals course provides all these prerequisites, but if you've learned these skills elsewhere, that's fine too. If you're unsure, feel free to contact us for an assessment.

Is this course suitable for complete beginners to programming?

If you've never programmed before, this course might be challenging but is still achievable with dedication. JavaScript is often people's first programming language, and we design our curriculum to accommodate those new to programming concepts.

However, if you're completely new to both HTML/CSS and programming, we recommend taking our HTML & CSS Fundamentals course first. This provides a gentler introduction to web technologies before diving into JavaScript.

What will I be able to build after completing this course?

By the end of this course, you'll be able to:

  • Create interactive web pages with dynamic content
  • Build forms with validation and user feedback
  • Create UI components like tabs, modals, sliders, and dropdowns
  • Fetch and display data from APIs
  • Implement client-side filtering and sorting of data
  • Create simple single-page applications

Your final project will be a complete interactive web application that demonstrates these skills and can serve as a portfolio piece for potential employers.

Will this prepare me for learning React or other frameworks?

Absolutely! A solid understanding of JavaScript is essential before learning any JavaScript framework like React, Vue, or Angular. This course specifically focuses on modern JavaScript features (ES6+) that are heavily used in these frameworks.

After completing this course, you'll have the necessary foundation to progress to our Advanced Frontend Frameworks course, which covers React in depth along with an introduction to other popular frameworks.

How much practice time should I allocate outside of class?

We recommend allocating at least 4-6 hours per week for practice and homework outside of the scheduled classes. Programming is a skill that requires practice, and the more time you can dedicate to coding, the more comfortable you'll become.

We provide weekly coding challenges and exercises that reinforce the concepts taught in class. Additionally, our instructors are available during office hours and via our online community platform to help with any questions that arise during your practice time.
