TypeScript

Develop robust code and explore TypeScript fundamentals

This two-day course with expert instructors helps JavaScript developers transition to TypeScript with confidence. Learn the skills to write clearer and more scalable code and discover the latest techniques to boost efficiency and improve project outcomes. 

Learning objectives
  • Compile TypeScript and configure project settings 
  • Apply strong typing with primitives, arrays and objects 
  • Use union types, aliases and interfaces effectively 
  • Implement type narrowing with guards and control flow 
  • Design flexible function types with generics 
  • Manipulate types using advanced utility types 
  • Develop TypeScript classes using access modifiers and inheritance 
  • Follow best practices to maintain cleaner codebases 

What you’ll learn

This course enables you to move beyond JavaScript by understanding the power of TypeScript. You’ll learn how to define custom types that exploit primitive types, array types, object types, union types, aliases, interfaces, and literal types. You’ll build skills to help reduce runtime bugs and simplify code maintenance. 

Master type safety and custom types

Learn how to use TypeScript’s powerful type system to eliminate common JavaScript pitfalls. You’ll define and apply a wide range of types, from primitives and arrays to unions, interfaces, and literal types. This will give your code more structure and predictability. By learning how to annotate and assert types, you’ll reduce runtime errors and make your codebase easier to maintain and scale. 

Implement type narrowing for smarter code

Understand how TypeScript infers types through control flow and logic, enabling you to create more precise, safer programs. You’ll explore type guards, truthiness checks, equality comparisons, and instanceof usage to effectively narrow types at runtime. This allows you to write code that adapts intelligently to the data it handles, without sacrificing type safety. 

Design flexible, reusable functions

Explore the design of advanced function types, including call and construct signatures, optional parameters, rest arguments, and generic functions. You’ll also handle complex scenarios like parameter destructuring and function overloading. These skills allow you to write flexible, efficient code that adapts to various use cases while maintaining strict type control.

FAQs

This course gives JavaScript developers a clear pathway into mastering TypeScript, covering everything from setup to complex type manipulation. You’ll learn how to exploit TypeScript to produce more advanced, efficient and robust code.  

What is TypeScript and why should I learn it?

TypeScript is a statically typed superset of JavaScript that reduces bugs and improves code maintainability. It’s increasingly used in enterprise applications and frameworks like Angular, React, and Vue. 

Is this course suitable if I already use JavaScript frameworks like React or Angular?

Yes. TypeScript is increasingly used in frameworks like React, Angular and Vue. This course strengthens your understanding of TypeScript’s type system and helps you write more maintainable code in these frameworks, especially as they evolve to support advanced TypeScript features. 

Will this course help me write more secure code?

Indirectly, yes. While not focused on security specifically, TypeScript’s static type checking can help prevent many common bugs that lead to vulnerabilities. You’ll learn to spot potential logic issues earlier, reduce reliance on runtime testing, and improve the reliability of your code. 

Does the course include any project work or mini applications?

While the course doesn’t include a full project build, you will work through a series of practical exercises that simulate real-world scenarios. These hands-on examples are designed to reinforce key concepts and give you confidence in applying what you’ve learned immediately. 

How does this course support long-term learning after it ends?

You’ll receive comprehensive course notes and example code that acts as a valuable reference. Plus, StayAhead provides post-course support, so if questions arise as you start using TypeScript in your projects, help is just an email or call away.
