JavaScript TypeScript curriculum: 5 modules over 5 days

Module 1 : Theme: Advanced JavaScript and modern patterns (ES2026, tools, deliverables)

Participants explore the latest 2026 JavaScript features, advanced patterns, and productivity tools. They complete practical exercises on complex data manipulation, new APIs, and performance optimization. Each session includes real-world enterprise cases and the production of reusable modules delivered at the end of the day.

Module 2 : Theme: Advanced TypeScript and strict typing (decorators, templates, deliverables)

This day covers advanced typing, template literal types, and decorators in depth. Learners work on real projects, configure strict rules, and generate dynamic types. Practical exercises enable them to secure legacy code and produce a production-ready typed library.

Module 3 : Theme: Next.js and TypeScript integration (SSR, API routes, deliverables)

Trainees design Next.js applications with advanced TypeScript. They implement server-side rendering, secure API routes, and image optimization. Practical workshops based on enterprise cases result in a complete, deployable full-stack application deliverable.

Module 4 : Theme: Testing, quality, and CI/CD for JavaScript TypeScript (tools, deliverables)

Participants set up advanced testing strategies with Jest and Playwright. They configure CI/CD pipelines, analyze code coverage, and automate reviews. Concrete exercises on professional projects enable delivery of a complete test suite and quality report.

Module 5 : Theme: Production deployment and optimization for JavaScript TypeScript (performance, deliverables)

The final day covers monitoring, bundle optimization, and deployment best practices. Learners finalize their project with performance metrics and enterprise recommendations. Each participant delivers an optimized and documented application.

Our method

How Learni guarantees the quality of your JavaScript TypeScript training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
