Core JavaScript
Learn JavaScript for dynamic web development and enhanced technical skills
This course offers a practical introduction to JavaScript for those new to the language or needing a refresher. With a focus on real-world, front-end development and browser-based interactivity, you’ll explore the core building blocks of JavaScript. Gain the skills needed to write structured, dynamic code with confidence.
Learning objectives
- Write JavaScript using ES6 standards
- Use variables and data types effectively
- Define and call functions
- Control program flow with conditions and loops
- Manipulate HTML elements with the DOM
- Handle user events
- Work with browser-based Web APIs
- Create simple interactive applications
What you’ll learn
Gain practical experience writing JavaScript code that responds to user input, includes dynamic page updates and uses browser features like local storage and key APIs. You’ll also learn the essential concepts behind functions, variables, program flow, and debugging in a modern JavaScript environment.
Introduction to JavaScript
You’ll begin by setting up your development environment and gaining a clear understanding of how JavaScript integrates with HTML and CSS. The course provides an introduction to JavaScript’s role in web development and explores the differences between browser-based and server-side (NodeJS) environments. By the end of this module, you’ll be writing and running simple scripts with confidence, ready to build functionality and interactivity into your own web pages.
Functions and programme logic
Discover how to write efficient, structured JavaScript by mastering functions and control flow. You’ll learn how to define and invoke functions using declarations, expressions, and arrow functions, gaining a clear understanding of when and why to use each. The course also covers how to pass and return data, handle parameters effectively, and navigate JavaScript’s approach to scoping.
Events and Web APIs
Learn how to make your applications interactive and responsive by working with browser events and built-in Web APIs. This part of the course focuses on using event listeners to detect and respond to user actions such as clicks, key presses, or form submissions. You’ll gain insights into how events propagate through the Document Object Model (DOM), and how to manage them effectively to deliver smooth user experiences. These skills allow you to create applications that not only react to user input but also store and process data with ease.
