How does preact compare to react-lite? about preact HOT 2 CLOSED

@andyhu I should clarify up-front: Preact is not just an attempt to perfectly emulate React's behavior in a small library size (although preact-compat probably is that attempt). It is an implementation of the concepts of React, but it is not free of opinions. There is a fairly complete list of differences between Preact and React on the wiki.

Here are some key differences:

Preact is faster

This standard benchmark shows Preact is more than 2x faster overall:

Preact is much smaller

Preact is 3.5Kb, react-lite is 17kb.

More Features

Preact actually has more features from React than react-lite does! It can render to a static HTML string via preact-render-to-string. Further, Preact supports isomorphic rendering, meaning your code on the client picks up where the server rendered markup leaves off - the first render on the client is a diff, instead of a replace. Also, instead of being a no-op as they are in react-lite, PropTypes are fully supported (ie, respected/validated) in preact-compat.

Preact is Modern

Preact is written in ES2015. It intentionally avoids bringing deprecated APIs into its core, instead leaving that work to preact-compat so that it is entirely optional. It is pluggable via vnode hooks, includes performance features like batching right out of the box, and works in IE9.
