Course overview
Write cleaner code with modern TypeScript techniques
This two-day, instructor-led course from ILX helps JavaScript professionals upskill with TypeScript. Explore modern techniques that make code easier to understand, test, and maintain in larger applications. Learn how to determine when a function type is needed and construct it correctly using generics where appropriate.
Learning objectives
- Set up TypeScript and manage configurations
- Use strong types with arrays, objects, and primitives
- Employ interfaces, aliases, and unions effectively
- Apply narrowing methods and logical type guards
- Build generic and reusable functions
- Master mapped and conditional utility types
- Implement classes using modern TypeScript syntax
- Adopt coding patterns for maintainability
What you’ll learn
Take your JavaScript to the next level by embracing TypeScript’s advanced features. Learn how to catch errors early and write code that scales across large applications. Exploit object type features including modifiers, index signatures, extensions and intersections, generics, and tuple types. Extend your technical skill set for stronger career progression.
Introduction to TypeScript
The ILX course opens with a practical introduction to TypeScript, highlighting how it differs from JavaScript and why adopting static typing enhances code reliability. You’ll walk through installation, configuration, and the TypeScript compilation process, gaining a working setup that’s ready for real-world use.
With an emphasis on tooling and strictness flags, this course sets the foundation for clean, maintainable code from day one.
Advanced object types and type manipulation
Explore how to design and manage complex data structures using TypeScript’s object type features. You’ll learn to apply optional and readonly modifiers, extend and intersect types, and use generics to build scalable components.
The course also covers mapped types, conditional types, and utility types, giving you powerful techniques to model sophisticated business logic and reduce duplication in large codebases.
Classes and best practices
Move beyond syntax and learn how to use classes effectively in modern TypeScript applications. Examine how to structure classes using constructors, access modifiers, static members, and abstract definitions.
You’ll also explore when and how to use arrow functions, parameter properties, and interfaces. Crucially, this module highlights real-world conventions and practices that help keep TypeScript codebases readable, reusable and consistent across teams.

FAQs
ILX’s TypeScript training gives JavaScript users a complete foundation in static typing and structured programming. The course builds real-world coding confidence and modern development fluency.
Is this course useful if I want to transition from JavaScript to TypeScript full-time?
Yes, this course is designed for developers ready to integrate TypeScript as a core part of their development stack. It equips you with the tools and understanding to replace or upgrade JavaScript codebases confidently using modern TypeScript practices.
Do I need to be a frontend developer to benefit from this course?
Not at all. While frontend developers using React, Angular or Vue will benefit, the course is equally valuable for backend or full-stack developers working with Node.js or TypeScript-based APIs. It’s ideal wherever JavaScript is used.
Will I get to practise as I learn, or is it mainly theory?
You’ll apply concepts immediately through practical live labs and coding exercises. Each module is structured to include time for experimentation and reinforcement, helping you build real-world confidence as you go.
Does this course align with TypeScript versions currently used in industry?
Absolutely. ILX ensures its course content is current and aligned with the latest TypeScript releases, tools and best practices. The course is regularly updated to reflect changes in the ecosystem.
Will this course help me work with TypeScript in large-scale projects?
Yes. The ILX TypeScript course covers scalable code design, advanced typing strategies, and best practices that are crucial for managing larger applications. You'll learn how to structure code for clarity, maintainability and long-term growth—skills directly transferable to enterprise-level projects.
