## Overview

This tree contains five small React applications: task management, a product basket, a people table with deletion, a user directory backed by an HTTP API, and a timer dashboard. Their principal workflows are browser interactions handled by each app; the task and user apps also load or update remote records. The sampled source shows the task and user API calls and the shop and timer app-level wiring. Several child component implementations were not sampled, so their internal behavior and additional connections are not asserted.

Main entry points: [`user-list/src/App.tsx`](https://github.com/spec12333/js-frontend/blob/main/user-list/src/App.tsx) (User data and API), [`ToDo-List/src/context/ToDoContextProvider.tsx`](https://github.com/spec12333/js-frontend/blob/main/ToDo-List/src/context/ToDoContextProvider.tsx) (Task state and API), [`simple-online-shop/src/App.tsx`](https://github.com/spec12333/js-frontend/blob/main/simple-online-shop/src/App.tsx) (Shop and basket state), [`timer/src/App.tsx`](https://github.com/spec12333/js-frontend/blob/main/timer/src/App.tsx) (Timer state and actions)
