Preact.js is a lightweight React alternative with the same API.

Similarities to React

• ES6 Class, hooks, and Functional Components

• Compatibility via a simple preact/compat alias

• JSX, VDOM, DevTools, HMR, SSR.

• Cross-browser compatibility

• Transparent asynchronous rendering with a pluggable scheduler

Differences from React

• Works in the browser without any transpilation steps

• Syntactic sugar

* `props`, `state` and `context` are passed to `render()`

* Standard HTML attributes like `class` and `for` can be used instead of `className` and `htmlFor`
