How Does React Render Work? - Next LVL Programming

How Does React Render Work? In this informative video, we’ll take a closer look at how React handles rendering and updates for your components. Understanding the rendering process is essential for anyone looking to improve their React applications. We’ll start by discussing the initial render, which occurs when your app starts, and how state changes can trigger re-renders. You’ll learn about the essential functions like createRoot and how they work to display your components on the screen.

Next, we’ll break down the rendering process itself, explaining how React calls your components and how this recursive process ensures that everything is displayed correctly. We’ll also touch on the important concept of committing to the DOM and how React efficiently updates it based on changes.

A significant part of our discussion will focus on reconciliation, where React compares the Virtual DOM with the actual DOM to apply only the necessary updates. This optimization leads to improved performance and a smoother user experience. We’ll also cover the importance of the key prop and lifecycle methods in enhancing efficiency during rendering.
