Web Application

A program that runs in a web browser, like Gmail, Twitter, or an online store.

Detailed Explanation

A web application (web app) is software that runs inside your web browser instead of as a traditional desktop or mobile app. Just like opening Gmail in Chrome, web apps are accessed via URLs and do not need to be installed.

Web apps have a Frontend (what you see) and a Backend (servers that power it). The frontend is built with HTML, CSS, and JavaScript. The backend processes data using SQL and databases, handles authentication, and provides information the frontend needs via APIs.

Full Stack developers build both sides. Next.js is a popular framework for building web apps. Event handlers make web apps interactive. Web apps are everywhere because they are accessible (just open a URL), easy to update (no installation required), and work across devices.
