Advance your JavaScript skills for practical application
Over four engaging days, this JavaScript Developer training gives you a comprehensive grounding in JavaScript. You'll gain the confidence and tools to write effective, modern code that’s ready for real-world projects.
Learning objectives
- Create and maintain modern web apps
- Work confidently with JavaScript data types
- Design functions and manage scope
- Control browser interactions and events
- Utilise object-oriented programming
- Leverage functional programming patterns
- Work with async code using Promises and async/await
- Develop modular apps with build tools
- Test JavaScript logic for accuracy
What you’ll learn
Gain essential JavaScript skills including DOM control, asynchronous logic, modular code design and more. This training is designed to help you apply concepts quickly to real work scenarios and boost your development proficiency.
JavaScript fundamentals and data handling
Understand how JavaScript underpins modern development by exploring its role in both browser and server environments. Learn to declare variables with var, let and const, work with built-in types like arrays and objects, and see how JavaScript’s dynamic typing provides flexibility in managing diverse data.
Logic control and functional structures
Gain confidence in shaping programme flow with conditions, loops and error management. This section also introduces core functional programming concepts, including immutability, pure functions and higher-order operations — allowing you to write predictable, testable code while managing common development tasks more elegantly.
Building with objects and modern syntax
Work with object templates, constructors, prototypes and ES6 classes to create structured, reusable components. Explore encapsulation, inheritance and composition, while applying modern syntax like destructuring and spread operators. This combination helps you design applications that are easier to maintain, extend and integrate into frameworks like React or Node.js.
Interfaces, modules and quality assurance
Learn how to connect JavaScript with the DOM to build interactive user experiences, handling events and browser APIs for responsive applications. You’ll also cover module systems, bundling, and TypeScript for professional workflows, finishing with testing methods that ensure your code is reliable, maintainable and production-ready.

Key facts
Ideal for
Anyone new to JavaScript or refreshing old skills, aiming to create or improve web apps with modern techniques.
Prerequisites
Basic HTML, CSS, and general programming knowledge is helpful. Courses such as Introduction to Programming – JavaScript, or HTML & CSS are a good foundation.
Learning experience
Our experienced trainers and interactive labs create a focused, practical environment – so you can put theory into practice from day one.
FAQs
This JavaScript course explores both essential and advanced concepts, helping you confidently build interactive web apps and fully understand JavaScript’s place in today’s development landscape.
What makes this course different from online video tutorials?
This course is delivered live by an experienced JavaScript developer, allowing for real-time interaction, feedback, and hands-on coding exercises. You’ll apply what you learn immediately with practical tasks, and not just watch someone else code.
Can this course help me prepare for a job in front-end development?
Absolutely. It covers the core language skills and patterns used in front-end roles, including DOM interaction, event handling, modular code, and asynchronous data flows. All critical areas for anyone building user-facing applications.
Is any software or setup required before the course begins?
Yes, we’ll provide a simple setup guide before the course starts. It includes installing a text editor and a modern browser. No paid tools are required as everything is based on freely available resources.
How interactive is the learning experience?
The course includes structured live labs and instructor-led exercises. You'll write and test your own code in real time, ask questions as you go, and receive personalised feedback from your tutor.
Does this course support long-term learning or just short-term skills?
The practical focus means you’ll leave with both immediate know-how and a solid foundation for continued growth, whether you're heading into frameworks like React, or building your own JavaScript projects.
“Really informative course, structured to support all forms of learning and at a good pace.”
Owen, Graduate Trainee Engineer, Utilities
“Good structure to course. Each technical aspect broken down by instructor and theory explained with practical examples, which aided understanding and provided guidance on best practice when applying in real life scenarios. Pace was good - fast enough to keep engaged, and not too overwhelming.”
