COME BOTHER ME IN OUR DISCORD AND CODE TOGETHER!

New to React and wondering how it all works? In this video, I break down the process of building a React app in the browser, giving you a clear understanding of what happens behind the scenes. Whether you're a beginner or looking to refresh your knowledge, this video is for you!

Starting from the user's interaction with a URL associated with your React application, we dive into the steps that occur during the app's initialization. From the browser requesting the necessary files from the server to the creation of the initial DOM and execution of JavaScript code, we cover it all.

I'll explain how React's virtual DOM comes into play, comparing it with the actual DOM and efficiently updating the page to reflect any changes. You'll also learn about the role of ReactDOM's .render() method, which mounts your React components onto the DOM.

Throughout the video, I provide valuable insights and tips, including how to optimize your app's performance by understanding the batching process for state updates. Plus, if you're familiar with server-side rendering (SSR), I touch upon how it alters this process.

Whether you're following along with my React course or simply seeking to demystify React, this video is a must-watch. Join me on this journey of understanding the inner workings of React and gain the confidence to build your own React applications.
