React JSX , Babel, React Components & Props Explained from Scratch | ReactJS Full Course #2

Learn React the RIGHT way - no memorization, just pure understanding! In this video, we dive deep into React fundamentals using a first-principles approach. Instead of just showing you "how" to write code, we explain "why" things work the way they do. 🔥 What You'll Learn in This Video: ✅ JSX - What It Actually Is • JSX is NOT HTML - proof with real examples • Why className instead of class • Why style is an object, not a string • Self-closing tags requirement • JavaScript expressions inside {} ✅ Babel - The Transpiler • What is Babel and why we need it • Transpiler vs Compiler - the difference • How type="text/babel" works • Runtime vs Build-time transformation ✅ JSX Expressions - The Complete Picture • What can go inside {} and WHY • Strings, Numbers, Arrays - what renders • Booleans, null, undefined - why they don't render • Objects - why they throw errors • Functions returning JSX ✅ React Components • Component = Function that returns JSX • Why capital letter is REQUIRED (not just convention) • How React.createElement handles components vs DOM elements • Component composition - components inside components ✅ Props - Passing Data to Components • Props as function parameters • Different data types in props (string, number, boolean, array, object, function) • Props are read-only - why? • Destructuring props • The children prop ✅ The Complete Flow • JSX → React.createElement() → React Element (Virtual DOM) → Real DOM • Who does what: Babel vs React vs ReactDOM • Recursive resolution of components ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 Why This Tutorial Is Different: Most tutorials tell you WHAT to do. This tutorial explains WHY. Why does JSX need Babel? Why can't objects be rendered in JSX? Why do component names start with capital letters? Why is style an object and not a string? If you want to truly understand React (not just copy-paste code), this video is for you. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 Who Is This For: Beginners starting their React journey Developers who know React syntax but don't understand the "why" Anyone tired of memorizing rules without understanding them Students preparing for frontend interviews ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ #react #reactjs #jsx #babel #javascript #webdevelopment #frontend #programming #reacttutorial #reactcomponents #props #webdev #coding #frontenddevelopment #learnreact #reactforbeginners #javascripttutorial #webdeveloper #softwaredevelopment #hindi Visit Strike: https://strikes.in/ Class start from 1 december Visit Coder Army Website: https://coderarmy.in/#home Course start date: 1 september Timing: 6pm (Mon-fri) Hackathon will be organised after course completion Join Premium Whatsapp Group: https://whatsapp.com/channel/0029Va6H...
