00:00:00 React.js is a game changer, a JavaScript library created by Facebook that powers some of the world's most dynamic user interfaces.
00:00:09 It's maintained by a strong open source community, constantly innovating with new features like server components, which simplify your backend workflow
00:00:18 by running React on the server.
00:00:20 And it might seem like React is borrowing PHP's homework for building server-driven websites.
00:00:26 But it's more like React speaking at PHP's notes, modernizing them so you spend less time reinventing the basics and more time building amazing apps.
00:00:36 Of course, React isn't alone.
00:00:39 Frameworks like Vue.js, Svelte, Astro, and Angular are also making waves.
00:00:44 But when it comes to popularity, React dominates.
00:00:48 Just look at the numbers.
00:00:49 42% of the developers on the Stack Overflow Developer Survey chose React.
00:00:54 and it is the biggest programming survey in the world, featuring all of the programming technologies.
00:00:59 So, for the React to be that high, which gives that number a lot of weight.
00:01:04 React has also topped the State of JS survey for 6 consecutive years.
00:01:09 as the JavaScript library of choice.
00:01:11 And with a good reason.
00:01:12 React is the backbone of key stacks like Mearn and Pern, extends to mobile development with React Native, and integrates seamlessly with modern frameworks
00:01:23 like Next.js for full stack development.
00:01:26 In short, learn React and you'll have the tools to build apps for web, mobile, and beyond.
00:01:33 It's your ticket to becoming the Swiss army knife of developers.
00:01:36 Now, let me show you what makes React so powerful with a project that I made specifically for my upcoming React.js Pro course to help you visually understand
00:01:46 React patterns in practice.
00:01:48 And it's built entirely in React.
00:01:50 This app showcases React's smooth instant updates.
00:01:55 You won't see a single page reload or a loading spinner, even when browsing different sections.
00:02:01 Everything happens dynamically on one page.
00:02:03 How?
00:02:04 Well, React uses JavaScript and the virtual DOM to make it all possible.
00:02:09 The virtual DOM is like a simplified map of your web page, a JavaScript object that mirrors the real DOM.
00:02:16 Here's why it's revolutionary.
00:02:19 When something changes, React creates a new virtual DOM element.
00:02:23 It then compares it to the old one to pinpoint the difference, and only the changed part of the real DOM is updated, making React blazingly fast.
00:02:32 Think of it as updating a single tile in a mosaic instead of repainting the entire wall.
00:02:38 And React doesn't demand much, just a solid understanding of JavaScript.
00:02:43 So if you're unsure about concepts like ES6 Plus syntax, pause this video right now and go check out my complete JavaScript Mastery course.
00:02:51 It'll make sure that you have all of the necessary prerequisite knowledge to be able to get the most out of this course.
00:02:57 And for a more focused approach, or if you want to have a reference guide always available, download my free Ultimate React.js guide,
00:03:04 linked in the description, packed with prerequisites, core concepts, and project ideas to get you started.
00:03:10 And now that you understand why React is so popular, let me teach you how to write React code and introduce you to its syntax.
00:03:18 We'll start with the basics and slowly move towards building our amazing movie application.
00:03:24 So, are you ready to react?
