A retro-styled calculator built with React, Babel, and Bootstrap 5—designed to evoke the tactile charm of 90s interfaces. It features responsive layout, keyboard support, and dynamic input handling with real-time evaluation. This project is part of the freeCodeCamp Front End Development Libraries certification.
Create a functional calculator using React and Babel that mimics the look and feel of classic 90s interfaces. The project needed to be responsive, keyboard-accessible, and capable of handling chained operations with clean UX.
Handling input logic for chained operations, preventing invalid expressions, and maintaining a responsive layout with retro styling. Ensuring keyboard support and managing state transitions after evaluation were key challenges.
Used React hooks for state management, Babel for JSX compilation, and Bootstrap 5 for layout structure. Styled with Courier New, inset shadows, and gradient buttons. Added keyboard event listeners and input sanitization for robust UX.
