#Hooks React hook is nothing but a JavaScript function 😀 . Yes, you read it right 👍 . It is a JavaScript function but has some special features. The 2 important react hooks are 1) useState() 2) useEffect() 👉 useState() -useState() hook is used to generate state variables. state variables maintain the state of the React component To use the useState() hook we have to import it into our project:- Syntax: import {useState} from "react"; we have to use {} brackets to import it, as it is a "named export" in react. Ex: to create a state variable const ExpData = ()=>{ const[data, setData] = useState(null); .......; .......; } In the above example, "data" is a state variable and to update the value inside it "setData()" function is used. what ever we give inside the brackets of useState() is the default value of the state variable here, data = null; To update the state variable "data" use "setData()" function. Ex: setData("Hello"), Here, In the "data" variable, "null" is replaced with the "Hello" word. 👉 What are the advantages of using useState() instead of a normal variable 1) State variables keep the UI in sync with the data. If the data is changed then the UI of the web page is also automatically changed. 2) When a state variable is updated every time, React re-renders the component in which it is defined, again on the webpage. In simple terms, If the value in the "state variable" is updated then the UI is also going to get updated with the value of "state variable". #React #frontend #webDevelopment #programming

🚀 **Mastering React: Frequently Asked Questions** 🚀 1. **What is React?** React is a JavaScript library for building user interfaces. It allows developers to create reusable UI components, making the code more predictable and easier to debug. 2. **What are Components?** Components are the building blocks of a React application. They can be either class-based or functional and help break down the UI into smaller, reusable pieces. 3. **What is JSX?** JSX is a syntax extension for JavaScript that allows you to write HTML directly within JavaScript. It's an elegant way to describe the UI structure. 4. **How Does State Work in React?** State is an object that holds information that may change over the lifetime of a component. In functional components, you manage state using the `useState` hook. 5. **What is Props?** Props (short for properties) are read-only attributes used to pass data from parent to child components. They help in making components dynamic and reusable. 6. **What is the Virtual DOM?** The Virtual DOM is a lightweight copy of the actual DOM. React uses it to optimize updates, ensuring that only the parts of the DOM that have changed are re-rendered. 7. **How to Handle Events in React?** Handling events in React is similar to handling events on DOM elements. You use camelCase syntax to define event handlers, e.g., `onClick`. 8. **What are Hooks?** Hooks are functions that let you use state and other React features in functional components. Popular hooks include `useState`, `useEffect`, and `useContext`. 9. **What is Context API?** Context API is a way to pass data through the component tree without having to pass props down manually at every level. It’s useful for global state management. 10. **How to Optimize Performance in React?** Performance can be optimized using techniques like code-splitting, memoization (`React.memo`), and lazy loading components. **What is a React Router?** React Router is a library that helps manage navigation in a React application. It enables you to create single-page applications with navigation without the page refreshing. #ReactJS #WebDevelopment #JavaScript #Programming #TechTips #FrontendDevelopment #SoftwareEngineering
