Here’s what each rule does:

• react/display-name: 2: Requires React components to have a displayName property (useful for debugging and React DevTools). Anonymous components in React.memo() or React.forwardRef() will trigger this error.
• react/jsx-key: 2: Enforces that elements in arrays/iterators must have a unique key prop. Prevents React rendering issues and performance problems.
• react/jsx-no-comment-textnodes: 2: Prevents accidentally rendering comment text as visible content (e.g., <div>// comment</div> would show ”// comment” on screen).
• react/jsx-no-duplicate-props: 2: Disallows duplicate properties in JSX elements (e.g., <div id="1" id="2" /> is an error).
• react/jsx-no-target-blank: 2: Requires rel="noopener noreferrer" when using target="_blank" on links to prevent security vulnerabilities (reverse tabnabbing).
• react/jsx-no-undef: 2: Prevents using undefined components in JSX (catches typos like <Buton> instead of <Button>).
• react/jsx-uses-react: 2: Marks React as used when JSX is present (prevents “React is defined but never used” errors). Set to 0 for React 17+ with new JSX transform.
• react/jsx-uses-vars: 2: Marks JSX component variables as used (prevents <MyComponent> from triggering “MyComponent is defined but never used”).
• react/no-children-prop: 2: Prevents passing children as a prop explicitly (<div children="foo" />) - children should be nested instead (<div>foo</div>).
• react/no-danger-with-children: 2: Prevents using dangerouslySetInnerHTML and children props together (they conflict - React doesn’t know which to render).
• react/no-deprecated: 2: Warns about deprecated React methods (componentWillMount, componentWillReceiveProps, etc.).
• react/no-direct-mutation-state: 2: Prevents directly mutating this.state (must use setState() instead). Only applies to class components.
• react/no-find-dom-node: 2: Prevents using deprecated ReactDOM.findDOMNode() - use refs instead.
• react/no-is-mounted: 2: Prevents using deprecated isMounted() method (anti-pattern that indicates problematic code design).
• react/no-render-return-value: 2: Prevents using the return value of ReactDOM.render() (it’s deprecated and will be removed).
• react/no-string-refs: 2: Disallows string refs (ref="myRef"), enforces callback refs or useRef instead.
• react/no-unescaped-entities: 2: Prevents unescaped HTML entities in JSX that look like typos (e.g., > or " appearing as text).
• react/no-unknown-property: 2: Prevents unknown DOM properties (catches class instead of className, for instead of htmlFor).
• react/no-unsafe: 0: When enabled, warns about unsafe lifecycle methods (componentWillMount, componentWillReceiveProps, componentWillUpdate). Set to 0 (disabled).
• react/prop-types: 2: Requires PropTypes validation for component props. Often disabled when using TypeScript.
• react/react-in-jsx-scope: 2: Requires React to be in scope when using JSX. Set to 0 for React 17+ with new JSX transform.
• react/require-render-return: 2: Enforces that render() methods in class components must have a return statement.
• react-hooks/rules-of-hooks: “error”: Enforces React Hooks rules: only call hooks at top level, only call from React functions. Critical for hooks to work correctly.
• react-hooks/exhaustive-deps: “warn”: Warns when dependencies are missing from useEffect, useCallback, useMemo dependency arrays. Helps prevent bugs from stale closures.
