  1. testing-library-docs

    docs site for @testing-library/*

    The dashboard component is now short not because the logic was split into sub-components, but because the logic was moved to where it belongs. Testing is the proof: the hook can be tested with a simple unit test, and the component can be tested with React Testing Library by passing mock data as props rather than mocking the entire data layer.

  3. React

    Discontinued The library for web and native user interfaces. [Moved to: https://github.com/react/react] (by facebook)

    React's official documentation covers component composition patterns and when to use children vs props for component flexibility.

  4. ESLint

    Find and fix problems in your JavaScript code.

    Splitting for file length alone, splitting before a pattern appears at least twice, and splitting in ways that produce tightly coupled pairs of components are the patterns most worth avoiding. ESLint with the react-hooks plugin helps catch when extracted hooks still have too many concerns, by flagging dependency arrays that have grown unwieldy.
