React Element Selector Query (RESQ)

resq (React Element Selector Query) is a JavaScript library designed to query React components and HTML elements within the React Virtual DOM, emulating the functionality of `querySelector` and `querySelectorAll` for native DOM elements. It provides `resq$` for selecting a single matching component and `resq$$` for selecting multiple matches, supporting advanced features like wildcard selector patterns, asynchronous waiting for React to initialize, and filtering results by component state or props. The library is currently stable at version 1.11.0 and requires React v16 or higher. Its primary use cases include automated testing, debugging, and advanced component introspection in client-side React applications. It offers a programmatic interface to the React component tree, allowing developers to access internal component data like props and state through its `RESQNode` return structure.
