YeboLearn Technology Stack: Built with Tomorrow's Technology Today

Executive Summary

YeboLearn runs on the same cutting-edge technology stack used by Netflix, Facebook, and Airbnb—not because it's trendy, but because it's proven to scale. While competitors struggle with PHP 5 and jQuery, we're deploying React 19, Node.js 18+, and AI models that would make Silicon Valley jealous. This isn't just a tech stack—it's a competitive weapon.

React 19 - The UI Powerhouse

Version: 19.0 (Latest stable) Why React 19:

Server Components: 50% faster initial load
Concurrent Features: Smooth UI even under load
Automatic Batching: Fewer re-renders
Suspense Everywhere: Better loading states
Built-in Transitions: Smooth animations

Competitive Edge: While competitors use outdated jQuery or Angular 1.x, we leverage React's ecosystem of 100,000+ packages and millions of developers.

TypeScript 5 - Type Safety at Scale
