JavaScript developers bring versatility across the entire development spectrum. They build responsive front-end interfaces using React, Vue.js, and Angular while handling server-side logic with Node.js and Express. These professionals create RESTful APIs, implement real-time features with WebSockets, optimize application performance, and integrate third-party services. They work with MongoDB, PostgreSQL, and MySQL databases while using modern tools like Webpack, Babel, and TypeScript to deliver production-ready code.
