Calculator App

Introduction

The Calculator App is a simple, full-stack application designed for educational purposes. It demonstrates the integration of a frontend and a backend service using modern web technologies and containerization with Docker. This app allows users to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The project serves as a hands-on example to learn about:

• Frontend Development:
  A user-friendly interface (built with technologies like React, if desired) that lets users interact with the calculator in a seamless way.

• Backend API:
  A Node.js-powered backend that handles the calculation logic, showcasing how to structure and manage server-side code.

• Containerization with Docker:
  Using Docker and Docker Compose to package, deploy, and run the application consistently across various environments.
