Course overview
Build interactive web apps with JavaScript
Our Core JavaScript course teaches the fundamentals of using JavaScript in browser-based applications. Through hands-on exercises, you’ll become confident in core techniques that support modern user interface development. Plus, learn about variables and data types, functions, program flow, the DOM (Document Object Model), and Web APIs (Application Programming Interface).
Learning objectives
- Understand modern ES6 syntax
- Access and manipulate the DOM
- Use core JavaScript data types
- Control flow with logic and loops
- Respond to browser events
- Structure code with functions
- Develop basic interactive features
- Use built-in browser APIs
What you’ll learn
Learn how to code dynamic behaviour into web pages using JavaScript. You’ll explore key programming concepts including variables, functions, and control flow, and gain practical experience working with the DOM, handling events and using browser APIs.
JavaScript essentials
Build your confidence by learning the fundamentals of the language. Explore how JavaScript fits within the broader landscape of web development, including how it works alongside HTML and CSS. You’ll be introduced to the syntax and structure of JavaScript code, learning how to write clean, readable scripts that run directly in the browser. By the end of the course, you’ll be ready to write scripts that bring web pages to life with interactivity and functionality.
Understanding data and variables
Learn how JavaScript handles data by exploring how to declare and use variables effectively. You’ll work with var, let, and const, understanding when to use each and how they influence the scope and behaviour of your code. This course introduces JavaScript’s key data types, including strings, numbers, Booleans, arrays, and objects, and shows you how they behave in real-world scenarios.
Manipulating the DOM
Discover how JavaScript interacts with the structure of a web page through the Document Object Model (DOM). You’ll learn how to locate, reference and update HTML elements in real time, allowing you to change text, apply styles or add and remove content dynamically. This gives you the power to build more interactive and responsive web experiences without needing to reload the page.

Our experienced trainers and interactive labs create a focused, practical environment – so you can put theory into practice from day one.
FAQs
The Core JavaScript course covers the essentials of browser-based scripting, from syntax and logic to page interactivity and built-in browser tools.
Is the Core JavaScript course appropriate for beginners?
Yes, it’s designed for those new to JavaScript who want to understand the language's role in creating interactive websites. However, we would recommend that you have some familiarity with HTML, CSS and basic programming.
What version of JavaScript does the course cover?
This course is based on ES6 specification, which forms the foundation of modern JavaScript. By using ES6 as the baseline, the course ensures you’re learning up-to-date techniques that reflect current industry standards and best practices.
Is this course focused on front-end or back-end JavaScript?
The primary focus of the course is front-end JavaScript, using the language to build and enhance interactivity features within the browser. While there is some introduction to using JavaScript with NodeJS to demonstrate different environments, the main emphasis is on building skills for client-side development.
