Counter App in React: Purpose & Features Explained

A Counter App is a simple interactive application that displays a number and provides controls to change it. In our React Counter App, the interface will show the current count and three buttons: “Increment”, “Decrement”, and “Reset”.

Clicking Increment will increase the number, Decrement will decrease it, and Reset will set it back to zero. The main purpose of this project is to illustrate state management and event handling in React.

It demonstrates how a component can hold state (the count) and update the view automatically when that state changes.

Aim of the project

By completing this project, you will gain experience in setting up a React development environment, writing React code, and deploying a live app.

Specifically, you will learn how to: create a new React project (with Create React App), define and use React components and hooks, manage component state with useState, handle user events (button clicks), organize the code directory, and finally publish the app on a free hosting service (Netlify).

The end result is a working Counter App that runs in any web browser (and stays live on Netlify), illustrating the full development workflow from setup to deployment.
