Vue Router
Vue Router is the official routing library for Vue.js applications, enabling developers to build single-page applications (SPAs) with client-side navigation. It maps application URLs to Vue components, allowing for dynamic page transitions without full page reloads. It supports features like nested routes, route parameters, navigation guards, and lazy loading for optimized performance.
Developers should learn Vue Router when building Vue.js SPAs that require multiple views or pages, such as dashboards, e-commerce sites, or admin panels, to manage navigation efficiently. It's essential for creating seamless user experiences with features like back/forward browser navigation and deep linking, and it integrates tightly with Vue's ecosystem for state management and component lifecycle.
