rc-util: Common React Utilities

rc-util is a foundational utility library within the React ecosystem, specifically developed to provide common helper functions and components for other React libraries (often those under the `react-component` organization like Ant Design). It offers a suite of low-level utilities such as `createChainedFunction` for combining multiple event handlers, a `deprecated` logger for warning about API changes, and `Portal` for rendering children outside the DOM hierarchy. The current stable version is `5.44.4`. While a specific, detailed release cadence for `rc-util` is not directly specified in the available metadata, the project is actively maintained, receiving updates to address various React development challenges and support newer React versions, as evidenced by related package activity. Its key differentiator lies in its focused, unopinionated approach, providing essential building blocks without imposing architectural patterns, making it a reliable dependency for complex UI component libraries.
