Preact Markup

Only re-renders when markup changes, optimizing performance through efficient DOM updates, as explicitly stated in the README's diffing renderer feature.

Maps custom elements in markup to Preact components, passing attributes as props for dynamic rendering, enabling declarative HTML structures with interactive UIs without manual DOM manipulation.

Removes script tags by default to prevent XSS attacks, with an optional `allow-scripts` prop for controlled JavaScript execution, balancing safety and flexibility.

Supports both XML and HTML parsing via the `type` prop, allowing developers to choose based on content strictness, as mentioned in the parsing options section.
