💵 Cash Register

A JavaScript-based cash register application that calculates change using real currency denominations. This project focuses on algorithmic problem‑solving, clean logic, and practical UI structure.

📌 Project Overview

The Cash Register project simulates how a real cash drawer returns change based on the purchase price, cash provided, and the available money in the drawer. It determines:

• Whether exact change can be returned

• How much change to give back

• Which denominations to use

• Whether the drawer should remain open or close

This project helped strengthen my understanding of JavaScript logic, arrays, objects, and conditional flow.

🧰 Features

• Calculates change using real U.S. currency denominations

• Determines drawer status: "OPEN", "CLOSED", or "INSUFFICIENT_FUNDS"

• Clean, readable JavaScript logic

• Simple UI for entering purchase amount and cash provided

• Responsive layout

• Realistic cash drawer simulation

🖥️ Technologies Used

• HTML5

• CSS3

• JavaScript (ES6+)
