Web development is a broad field that encompasses the creation and maintenance of websites and web applications. It is divided into three main areas:

Frontend Development: Focuses on the user interface (UI) and experience (UX). It involves languages like HTML, CSS, and JavaScript, along with frameworks like React, Vue.js, and Angular. Topics include responsive design, animations, and accessibility.

Backend Development: Deals with server-side logic, databases, and APIs. Popular technologies include Node.js, Fastify, Python (Django/Flask), and PHP. Key areas include authentication, database management, and API development.

Full Stack Development: Combines frontend and backend expertise, enabling developers to build end-to-end web solutions. Stacks like MERN (MongoDB, Express, React, Node.js) and JAMstack (JavaScript, APIs, Markup) are commonly used.

Additional aspects of web development include performance optimization, version control with Git, UI/UX design using tools like Figma, and deployment to platforms like Vercel or AWS.

Web development is ever-evolving, driven by new frameworks, tools, and best practices, making continuous learning essential.
