Announcing XHP-JS: Building efficient user interface components with Hack, React, and XHP

Introduced XHP-JS, a library that enables the creation of efficient user interface components by combining Hack, React, and XHP. This allows for asynchronous server-side rendering with XHPAsync, integration of client-side logic into XHP components using XHPJSCall, and the creation of React components from Hack code using XHPReact. It also provides mechanisms for integrating existing non-XHP markup and Bootstrap components.
