Frontend: what users see and interact with. Technologies: HTML, CSS, JavaScript, React/Vue/Svelte. Runs in the browser. Backend: server-side logic, databases, APIs. Technologies: Node.js, Python, Go, PostgreSQL. Runs on servers. Full-stack: both. The line is blurring: Next.js and similar frameworks let you write frontend and backend in the same project. For career flexibility, learn full-stack with a frontend emphasis.
