📌 Project Overview

Built using HTML, Vanilla JavaScript, and Tailwind CSS, the application fetches real-time data from the REST Countries API to display key details such as population, capital, region, languages, and flags.

GeoVault focuses on providing a smooth user experience through dynamic features like search, filtering, and sorting, all implemented using JavaScript array higher-order functions (filter, sort, map, etc.).

The goal of this project is to demonstrate strong fundamentals of API integration, DOM manipulation, and modern UI design, while building a practical and visually appealing data-driven application.
