This Skill provides comprehensive assistance for React development, covering components, hooks, state management, and best practices. It helps developers efficiently build interactive user interfaces, reducing complexity and accelerating frontend development.
useState, useEffect, and custom hooks.import React, { useState } from 'react';
function Counter() { const [count, setCount] = useState(0);
return ( <div> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}> Click me </button> </div> ); }
export default Counter;

React components manage state using the useState hook to store and update data, with setters triggering re-renders. Use useState to create stateful functional components, useEffect for side effects, and useReducer for complex state logic. This approach enables interactive UIs without class syntax.
Pass data to components via props as function parameters and handle events by passing callback functions to element handlers like onClick. React's event system automatically binds handlers to the component instance, enabling parent-child communication and user interaction responses.
Debug React apps by using browser DevTools to inspect component trees, check prop values, and trace state changes. React DevTools extension shows component hierarchy and hook values. Console logging and breakpoints reveal rendering behavior and event flow for diagnosing UI issues.
Yes, hooks compose freely within functional components. useState manages component state while useEffect handles side effects like data fetching and subscriptions. Combine them to create stateful, effect-aware components with clear separation of concerns and predictable lifecycle behavior.
Declarative UI describes what the interface should look like based on current state; React handles DOM updates automatically. Imperative approach manually manipulates the DOM. React's declarative model reduces bugs, improves maintainability, and makes component logic easier to reason about and test.
JSX is React's recommended syntax for writing component markup alongside JavaScript logic, making code more readable and intuitive. While not strictly required—you can use React.createElement—JSX simplifies component development and is standard across the React ecosystem.
