HTMLJS Parser

The `htmljs-parser` is a specialized HTML parser designed to understand and process both standard HTML elements and embedded JavaScript expressions, particularly within attribute values and placeholders. It forms a core component of the Marko framework. The current stable version is `5.10.2`, with a consistent release cadence of frequent patch updates and minor versions introducing new validation APIs and parsing refinements. Its primary differentiator lies in its ability to deeply integrate JavaScript expression parsing directly into the HTML parsing stream, enabling advanced templating and reactive UI paradigms that extend beyond traditional HTML parsing capabilities. It is well-suited for environments requiring the compilation or processing of HTML containing dynamic JavaScript logic.
