React Props Explained: Understanding Properties in React

React Learning Series | Day 10 – Forms in React (Controlled Components) ->In React, forms are used to collect user input such as text, email, and passwords. ->React uses controlled components, where form data is managed using state. ->This gives full control over input values and behavior. Example: import { useState } from "react"; function Form() { const [name, setName] = useState(""); return ( <div> <input type="text" value={name} onChange={(e) => setName(e.target.value)} /> <p>Hello, {name}</p> </div> ); } Explanation: --useState stores input value --onChange updates state --UI updates automatically when user types Why Forms are Important: ✔ Handle user input ✔ Build interactive applications ✔ Enable validation and data control --->Controlled components make form handling predictable and efficient in React. 📌 Day 10 of my React Learning Series #ReactJS #ReactDeveloper #FrontendDevelopment #WebDevelopment #JavaScript #CodingJourney #LearningInPublic #DeveloperJourney #TechLearning #LinkedInSeries 🚀

While learning React, I explored different types of Hooks and realized how powerful they are for managing state and logic inside functional components. Here are some important React Hooks that every developer should understand: 1️⃣ useState Used to create and manage state inside a component. Example: counters, form inputs, toggles. 2️⃣ useEffect Used for handling side effects like API calls, timers, or updating the DOM after rendering. 3️⃣ useContext Helps share data between components without passing props manually through every level. 4️⃣ useRef Used to directly access DOM elements or store values that don’t trigger re-renders. 5️⃣ useMemo Optimizes performance by memoizing expensive calculations. 6️⃣ useCallback Returns a memoized version of a function to prevent unnecessary re-renders. What I like about Hooks is how they make React components simpler, cleaner, and easier to manage compared to class components. Understanding hooks really helps in building scalable and maintainable React applications. Still exploring more and building projects while learning. 🚀 #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #CodingJourney #LearnInPublic

React Learning Series | Day 8 – Understanding PropTypes ->In React, PropTypes are used to validate the type of props passed to a component. ->They help developers ensure that components receive the correct type of data, reducing bugs during development. ->PropTypes act as a type-checking mechanism for React components. Example: import PropTypes from "prop-types"; function User({ name, age }) { return ( <h2> {name} is {age} years old </h2> ); } User.propTypes = { name: PropTypes.string, age: PropTypes.number, }; Explanation: --PropTypes.string ensures the value must be a string --PropTypes.number ensures the value must be a number --If incorrect data is passed, React shows a warning during development Why PropTypes matter: ✔ Helps detect errors early ✔ Improves component reliability ✔ Makes code easier to understand --->PropTypes help build safer and more predictable React components. 📌 Day 8 of my React Learning Series #ReactJS #ReactDeveloper #FrontendDevelopment #WebDevelopment #JavaScript #CodingJourney #LearningInPublic #DeveloperJourney #TechLearning #LinkedInSeries 🚀

🚀 React Learning Journey (Day Update) Today I spent time understanding the core fundamentals of React — trying to build a strong base before jumping into advanced topics. Here’s a quick summary of what I explored 👇 What is React?:- A JavaScript library for building UI using reusable components. Components:- Break the UI into small reusable pieces. function Welcome() { return <h1>Hello React</h1>}; JSX & Rules:- Write HTML inside JavaScript (with some rules like className, single parent, etc.) <h1 className="title">Hello</h1> Props (Data Passing):- Send data from parent to child component. function User({ name }) { return <h2>{name}</h2>}; Conditional Rendering:- Show UI based on conditions. {isLoggedIn ? <p>Welcome</p> : <p>Login</p>}; Looping Data (map):- Render lists dynamically from arrays or objects. {items.map(item => <p key={item.id}>{item.name}</p>)}; Small concepts individually, but together they form the foundation of building real-world React applications. Still learning, still building. 🚀 #ReactJS #JavaScript #WebDevelopment #LearningJourney

React Learning Series | Day 9 – Conditional Rendering ->In React, conditional rendering allows components to display different UI based on certain conditions. ->It helps create dynamic and responsive user interfaces. ->You can use JavaScript conditions like if, ternary operator, or && operator inside JSX. Example: function LoginStatus({ isLoggedIn }) { return ( <div> {isLoggedIn ? <h2>Welcome Back!</h2> : <h2>Please Login</h2>} </div> ); } Explanation: --If isLoggedIn is true → shows “Welcome Back!” --If false → shows “Please Login” Why Conditional Rendering is Important: ✔ Displays dynamic content ✔ Improves user experience ✔ Controls UI based on state or props --->Conditional rendering makes React apps interactive and user-friendly. 📌 Day 9 of my React Learning Series #ReactJS #ReactDeveloper #FrontendDevelopment #WebDevelopment #JavaScript #CodingJourney #LearningInPublic #DeveloperJourney #TechLearning #LinkedInSeries 🚀

Most tutorials teach you what to build. Today I finally understood how things actually work under the hood. Day 4 of my React learning journey 🚀 Here’s what I worked on: • Built Create & Read functionality from scratch • Split logic into two separate components (cleaner + reusable) • Learned how to use React Hook Form • Understood how forms are managed efficiently using hooks Key insight: Handling forms in React doesn’t have to be messy. With the right approach (and tools like React Hook Form), you stop fighting state management… and start controlling it. Real moment: At first, managing inputs and state felt confusing — too many moving parts. But once I connected how hooks simplify the flow, everything started making sense. That shift from confusion → clarity was the real win today. Still early in the journey, but now I can see how real-world apps handle user data step by step. Building slowly. Understanding deeply.

Today’s React Learning Update 🚀 Today I continued practicing React by building a small project and learning some important concepts. What I learned today: • Display countries using fetch and use() in React • Show country flags and handle possible data errors • Apply styling in React with a 3-column layout and conditional text • Use conditional CSS and toggle state on click • Lift up state and pass handlers as props • Advanced: lift up state in arrays by comparing references • Manage flags with immutable array updates • Deploy the Rest Countries project to Netlify / Surge Each small project helps me understand React concepts more clearly and improve my frontend development skills. Looking forward to building more! 💻 Live Link: https://lnkd.in/gH_ChEBf #React #FrontendDevelopment #JavaScript #WebDevelopment #LearningJourney

⚡Day 1 of My React Learning Journey: What is React? I've started learning React today, and here's a simple breakdown What is React? React is a JavaScript library used to build dynamic and interactive user interfaces, especially for single-page applications (SPAs). Why is React so popular? Component-based architecture (reusable Ul parts) Virtual DOM for faster performance Easy to build scalable applications Strong community support Key Concept Instead of updating the entire page, React updates only the parts that change - making apps faster and smoother Simple Example function App() { } return <h1>Hello, React!</h1>; My Takeaway: React makes Ul development more structured and efficient compared to plain JavaScript. This is just the beginning-next I'll be learning about JSX!⚡ + Follow my journey as I learn React step by step #React #JavaScript #WebDevelopment #Frontend #LearningInPublic #100DaysOfCode

🚀 Understanding the React Component Lifecycle with Hooks When I first started learning React, one thing confused me a lot: When exactly do hooks run? Sometimes my useEffect ran twice. Sometimes state updates caused unexpected re-renders. And debugging it felt like chasing a ghost in the code. 😅 After spending time digging into it, I realized something simple: React components basically go through three main phases. 1️⃣ Mounting – The component is created This is when the component first appears on the screen. During this phase: useState initializes state useContext reads context useEffect([]) runs once after the first render 2️⃣ Updating – The component re-renders This happens whenever something changes. For example: State changes Props change Context changes React re-renders the component and then runs: useEffect([dependency]) only if the dependency changed. 3️⃣ Unmounting – The component is removed When a component disappears from the UI. This is where cleanup functions become important. Example: Remove event listeners Cancel API requests Clear intervals That’s why useEffect can return a cleanup function. 💡 One small insight that helped me: Think of React components like a life cycle: Born → Update → Die Once this mental model clicks, hooks become much easier to understand. I made this visual guide to simplify the concept 👇 💬 Curious to know: When learning React, which hook confused you the most? useEffect useState useContext Something else?

As part of my MERN stack learning journey, today I explored several core concepts of React. This session focused on: ✅ React Components ✅ Props ✅ Event Handling ✅ React Hooks – useState, useEffect, and use Along with understanding what these concepts are and when to use them, I implemented them through a few small practice projects to reinforce my learning. Working on these mini projects helped me better understand how React components interact and how hooks manage state and side effects in real applications. I strongly believe that the best way to learn development is by building projects and solving real problems. 🔗 Project links are shared below. https://lnkd.in/gpj9nFdw #React #MERNStack #FrontendDevelopment #JavaScript #LearningInPublic #WebDevelopment
