ES Modules in React: Importing and Exporting Code

Still writing only JavaScript and wondering where to begin with React? You're not behind. You just need the right starting point. 🎯 We're hosting a FREE Webinar this 5th February at 11 AM, designed specifically for JavaScript developers taking their very first step into React. What we'll cover: ▸ What React is & why every developer needs it ▸ Core React basics, explained simply & clearly ▸ Writing your first real React code ▸ The clear path forward after the basics Just bring your JavaScript basics and the willingness to learn 🙌 🔗 Register FREE → https://lnkd.in/dB-7pBqk #React #ReactBasics #JavaScript #FrontendDevelopment #LearnReact #WebDevelopment #BeginnerDeveloper #FreeWebinar #DeveloperRoadmap #TechWebinar

React doesn't update the entire page. It's way smarter than that. Here's what actually happens behind the scenes in 6 simple steps: 📋 Virtual DOM — a lightweight JS copy of the real DOM 🔍 Diffing — comparing old vs new to spot changes 🔄 Reconciliation — the full compare-and-update cycle ✏️ JSX — looks like HTML, but it's JavaScript 🔧 Babel — translates JSX into plain JS before the browser sees it 🚀 The Flow — JSX → Babel → Virtual DOM → Diff → Real DOM Save this. The next part covers Components, Props & State. ♻️ Repost to help someone learning React. #React #VirtualDOM #JavaScript #WebDevelopment #Frontend #LearnToCode

Many JavaScript developers learn call(), apply(), and bind(). But remembering the difference can still be confusing. Here’s the simplest way to remember them 👇 👉 call() → calls the function immediately (arguments one by one) 👉 apply() → calls the function immediately (arguments as an array) 👉 bind() → returns a new function without calling it Once you understand these, 'this' in JavaScript becomes much easier. I wrote a simple beginner-friendly guide explaining 'this' with clear examples. I’ll share the article in the comments. Which one confused you the most when you first learned JavaScript — call(), apply(), or bind()? #javascript #webdevelopment #frontenddevelopment #reactjs

Many beginners think querySelector() in JavaScript and useRef() in React do the same thing. But React uses a Virtual DOM, so direct DOM manipulation can break React’s flow. That’s why useRef() gives controlled access to the DOM while keeping React’s architecture intact.

🚫 Do Not Overuse <div> in React When working with HTML, we often use <div> to wrap multiple elements. But in React, unnecessary <div> elements can create extra nodes in the DOM. 💡 React introduced Fragments (React 16.2) to solve this problem. Why use React Fragments? • No extra DOM nodes • Cleaner and less cluttered DOM • Slightly better performance • Easy way to group multiple elements React also provides a Fragment shorthand (<> </>) which makes code cleaner and easier to write. 📌 I’ve explained this concept in a simple swipe PDF for beginners. #React #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #MohitDecodes

Every senior developer I've met secretly hates JavaScript but keeps using it because there's no real alternative for the browser. It's not a choice. It's a hostage situation. 💀 TypeScript is just JavaScript with a blindfold on 😂 it doesn't fix the chaos underneath. Prove me wrong 👇 #JavaScript #TypeScript #SoftwareEngineering #HotTake

🌐 Understanding JSX in React Today I learned how JSX allows us to write HTML inside JavaScript. 1)Embedding JavaScript inside {} 2)Single root element rule 3)How React converts JSX into JavaScript ✔ JSX = Syntactic sugar ✔ It gets compiled by Babel ✔ It becomes React.createElement() ✔ React then creates Virtual DOM objects Now React UI development feels more practical and clear. #ReactJS #JSX #FrontendDevelopment #LearningJourney

If anyone is interested in developing their skills in React.js, a quick thought based on my experience that might be helpful. 💬 Here are some tips for developing this skill: 1) Start with learning and practicing JSX , Components and props. 2) Go for hooks and state management then. React is different from Javascript, since it uses virtual dom. #javascript #react #webdevelopment
