Vue.js (commonly referred to as Vue; pronounced "view"[6]) is an open-source model–view–viewmodel front end JavaScript framework for building user interfaces and single-page applications.

[6] Advanced features required for complex applications such as routing, state management and build tooling are offered via officially maintained supporting libraries and packages.

[18][19] Version names are often derived from manga and anime series, with the first letters arranged in alphabetical order.

A virtual Document Object Model (or "DOM") allows Vue to render components in its memory before updating the browser.

[47] Vue provides a variety of ways to apply transition effects when items are inserted, updated, or removed from the DOM.

These frameworks often extend or enhance features available through native web technologies, such as routing, component-based development, and state management.

While native web standards, including Web Components, modern JavaScript APIs like Fetch and ES Modules, and browser capabilities like Shadow DOM, have advanced significantly, frameworks remain widely used for their ability to enhance developer productivity, offer structured patterns for large-scale applications, simplify handling edge cases, and provide tools for performance optimization.

[53][54][55] Frameworks can introduce abstraction layers that may contribute to performance overhead, larger bundle sizes, and increased complexity.

Modern frameworks, such as Vue 3, address these challenges with features like concurrent rendering, tree-shaking, and selective hydration.

While these advancements improve rendering efficiency and resource management, their benefits depend on the specific application and implementation context.

Framework choice depends on an application’s requirements, including the team’s expertise, performance goals, and development priorities.
