Definition
Vue.js is an open-source JavaScript framework for building user interfaces and single-page applications. It is known for its simplicity, flexibility, and progressive adoption model, meaning developers can use it for small interactive components or scale it to full-featured applications.
Vue.js uses a component-based architecture, making it easy to organise code into reusable parts. Its reactive data-binding system ensures the user interface updates automatically when underlying data changes, providing a smooth and efficient development experience.
Advanced
At an advanced level, Vue.js offers features such as Vue Router for navigation, Vuex for state management, and server-side rendering with Nuxt.js. Its virtual DOM implementation ensures efficient rendering, while tools like Vue CLI and Vite streamline development and build processes.
Vue supports TypeScript, composition API, and custom directives for advanced flexibility. It is widely used in enterprise applications, SaaS platforms, and e-commerce websites due to its balance of simplicity and scalability.
