## Description

Snabbdom is a virtual DOM library and DOM diffing engine used to create and update user interfaces by synchronizing a virtual tree with the browser. It functions as a modular UI framework that provides a system for generating virtual nodes and transforming them into actual browser elements.

The project features a modular architecture that separates core rendering logic from optional components. It includes a dedicated SVG rendering engine for managing scalable vector graphics within a virtualized document object model.

The library covers a broad range of capabilities, including lifecycle hook execution for intercepting node creation and removal, and server-side hydration to convert existing HTML elements into virtual nodes. It also provides utilities for attribute and property management, event listener binding, and the use of fragments to group elements without adding wrapper nodes to the layout.

Performance is managed through key-based node tracking and sub-tree rendering optimizations to minimize the set of changes applied to the physical interface.
