TypeScript curriculum: 5 modules over 5 days
Module 1 : Advanced TypeScript Types: Unions, Intersections, and Literals (practical exercises, UML diagrams)
Discover unions and intersections to model complex data, apply them via exercises on real APIs, build type guards to validate user inputs, generate type diagrams with tools like TypeScript Playground, analyze avoided runtime error cases, produce a first deliverable with a robust typed validator, integrate concrete e-commerce project examples to anchor professional development skills.
Module 2 : Generics and TypeScript Utility Types: Parametrization and Mapped Types (advanced exercises, reusable templates)
Dive into generics to create reusable components, manipulate Partial, Pick, and Omit on large datasets, develop typed higher-order functions, test with Jest to validate constraints, explore patterns like Builder through collaborative workshops, produce custom utilities for React hooks, apply to enterprise scenarios for immediate and certifiable upskilling.
Module 3 : TypeScript Modules and Namespaces: Advanced Organization (Next.js integration, legacy code refactoring)
Structure projects with advanced ES and CommonJS modules, implement barrels for optimized exports, integrate TypeScript into Next.js for typed SSR, refactor legacy JavaScript code in practical workshops, manage ambient declarations for third-party libs, deploy a prototype app with typed routing, analyze maintainability metrics, deliver a production-ready reusable module in a professional context.

FAQ
TypeScript: frequently asked questions
Which tools are used in TypeScript training?+
Hands-on work runs on practical exercises, UML diagrams, advanced exercises, reusable templates, next.js integration and legacy code refactoring. Those tools come from the TypeScript program itself, delivered on site over 5 days, so participants practise on the stack they will use at work.
What can participants do after TypeScript training?+
They can master advanced types and unions in TypeScript to strengthen professional skills in scalable development, develop powerful generics and utility types to optimize code in enterprise contexts and implement advanced modules and namespaces to structure certifiable TypeScript projects. Those are the stated objectives of the TypeScript program at Advanced level, checked by the end-of-session assessment.
What does the TypeScript program cover, day by day?+
Day 1: Advanced TypeScript Types: Unions, Intersections, and Literals (practical exercises, UML diagrams).

Day 5: TypeScript Capstone Project: Full Architecture with Next.js (Vercel deployment, E2E tests, code review). The TypeScript program runs over 5 days, delivered on site.
How is TypeScript training assessed?+
Assessment relies on daily interactive quizzes on advanced types and generics to validate learning outcomes, end-of-training project graded on TypeScript architecture and Next.js integration and oral interviews and code reviews to certify professional skills. Learni issues a completion certificate together with the individual assessment report at the end of the TypeScript program, which an L&D team can file as evidence.
How much does TypeScript training cost per participant?+
TypeScript training costs $5,775 per participant. For an in-company team, the flat rate starts at $10,395 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
