Unlike typical virtual DOM libraries like React, Mithril, Virtual-dom, Snabbdom and Om, Inferno uses techniques to separate static and dynamic content. This allows Inferno to only "diff" renders that have dynamic values.
Glimmer is one of the fastest DOM rendering engines, delivering exceptional performance for initial renders as well as updates.
Mithril is around 12kb gzipped thanks to its small, focused, API. It provides a templating engine with a virtual DOM diff implementation for performant rendering, utilities for high-level modelling via functional composition, as well as support for routing and componentization.
