The Learni story
Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1JavaScript Fundamentals: Syntax, Variables, and Control Structures (VS Code, Browser Console)
Discover the basics of JavaScript through practical exercises on variables, data types, and operators, using VS Code and the browser console. Explore loops, if/else conditions, and switch statements to structure your first code, with concrete examples like a simple calculator. The trainer guides each step, provides real-time corrections, and supplies reusable templates to anchor skills from the first day.
Module 2JavaScript Functions and Objects: Modularity and Data Manipulation (Arrays, JSON Objects)
Dive into functions, variable scopes, and callbacks to modularize your JavaScript code effectively. Manipulate arrays and objects with map, filter, reduce in exercises on dynamic lists, such as a task manager. Integrate JSON for data exchange, test live with common errors corrected collectively, and produce a functional deliverable ready for a professional portfolio.
Module 3JavaScript DOM Manipulation: Element Selection and Modification (querySelector, addEventListener)
Learn to interact with the DOM in JavaScript using querySelector and getElementById to select and dynamically modify HTML elements. Implement events like click and input with addEventListener on an interactive form, manage real-time updates. Solve practical cases like a responsive dropdown menu, with console debugging and performance optimization, for immediately visible results on your web pages.
Module 4JavaScript Projects: Full Integration and Best Practices (ES6, Advanced Debugging, Deployment)
Build a final JavaScript project integrating everything: a game or todo-list with localStorage, events, and CSS/JS animations. Adopt ES6 best practices like const/let, arrow functions, and basic async/await. Debug with Chrome DevTools breakpoints, test cross-browser, and deploy on GitHub Pages. Receive personalized feedback and a certifying attestation to value your new skills in the workplace.

Our method
Training quality, guaranteed at every step
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.
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.
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.
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.
