Who it’s for
Engineers with the listed foundations who want to deepen this skill or apply it in a different stack.
Starting point: IntermediateWeb development · Corporate training
Sample curriculum
TypeScript
Make JavaScript applications easier to change with useful types, explicit contracts, and safer refactoring.

A practical destination
Skills to practise.
The sample path works towards these capabilities. Final goals reflect your team’s starting point and agreed scope.
- 01
Use strict types to make application contracts visible.
- 02
Model alternative states without losing useful type information.
- 03
Refactor a feature while checking runtime data at its boundaries.
Sample curriculum
Follow the learning route.
Each module connects the concepts to practical work. Open a module to explore both.
01Module 1TypeScript foundations
Concepts to understand
- Compiler setup and strict checking
- Inference, primitive types, arrays, and tuples
- Function signatures and optional properties
Practical work
Type a small JavaScript utility under strict checking. Explain what the compiler can infer and where an explicit signature helps.
Show the result. Explain one decision. Identify what you would improve.
02Module 2Modeling application data
Concepts to understand
- Interfaces and type aliases
- Union and intersection types
- Discriminated unions and narrowing
Practical work
Model loading, success and error states as a discriminated union. Make an invalid state difficult to represent.
Show the result. Explain one decision. Identify what you would improve.
03Module 3Reusable types
Concepts to understand
- Generics and constraints
- Utility types and mapped types
- unknown, never, and runtime validation boundaries
Practical work
Create a reusable generic utility and apply a useful constraint. Compare it with an overly permissive version.
Show the result. Explain one decision. Identify what you would improve.
04Module 4TypeScript in a project
Concepts to understand
- Typing asynchronous APIs
- Framework and library integration
- Migration, debugging, and refactoring
Practical work
Migrate an API-driven feature to TypeScript. Validate incoming data separately from its compile-time types, then refactor a consumer.
Show the result. Explain one decision. Identify what you would improve.
A sample project
Bring the skills together.
Migrate a JavaScript feature to TypeScript with typed API boundaries and reusable generic utilities.
Shorter engagements can focus on selected exercises. A larger, learner-owned capstone can be scoped for a longer programme.
Review the work & reasoning
Four useful questions.
- 01
Does the work meet the agreed requirements?
- 02
Can the learner explain the key decisions and trade-offs?
- 03
What happens with invalid input, failure or an unexpected condition?
- 04
What would they change or explore next?
