## Overview

This is a React e-learning site with course content, topic quizzes, an ebook library, and account/profile pages; its Express backend excerpt includes registration, sign-in, and feedback endpoints. The main user journey is navigating the site to a course or assessment and viewing its learning material or results. Course-to-player composition and quiz routing are visible in sampled files; most page internals and frontend-to-backend request wiring were not sampled, so those connections are omitted.

Main entry points: [`src/App.jsx`](https://github.com/venkatarao-mettela/learning_website/blob/main/src/App.jsx) (Routes and app shell), [`back-end/index.js`](https://github.com/venkatarao-mettela/learning_website/blob/main/back-end/index.js) (Express API), [`src/main.jsx`](https://github.com/venkatarao-mettela/learning_website/blob/main/src/main.jsx) (Auth0 provider), [`src/Components/Course/Javaprog.jsx`](https://github.com/venkatarao-mettela/learning_website/blob/main/src/Components/Course/Javaprog.jsx) (Course lessons)
