📌 Extra Information for Beginners | React JS Basics Explained in Just 120 Seconds

React is a JavaScript library, not a full framework like Angular.

It’s best for building single-page applications (SPAs) that need fast, smooth navigation.

You only need basic HTML, CSS, and JavaScript knowledge to get started with React.

Tools like Vite, Create React App, or Next.js help you quickly set up projects without complex configurations.

React has one of the largest developer communities, making it easy to find support, tutorials, and open-source libraries.

ReactJS is one of the most popular
0:02
JavaScript libraries for building modern
0:05
user interfaces. It was created by
0:07
Facebook and has become the go-to choice
0:10
for developers around the world. At its
0:13
core, React is all about components.
0:16
Think of components as reusable building
0:19
blocks, like Lego pieces that come
0:22
together to form a full application.
0:24
Each component manages its own
0:26
structure, style, and behavior, allowing
0:29
developers to build complex UIs with
0:32
ease.
0:33
Now, let's talk about the virtual DOM.
0:36
Instead of directly updating the real
0:38
DOM, React uses a virtual DOM, which is
0:41
a lightweight copy of the actual DOM.
0:44
When changes happen, React compares the
0:47
new virtual DOM with the old one and
0:49
updates only what's necessary. This
0:52
makes React super fast and efficient,
0:54
ensuring that your applications run
0:56
smoothly, even as they grow in
0:58
complexity.
2:01
empowers developers to create
2:02
applications that are not only
2:04
functional, but also maintainable and
2:07
scalable. So whether you're building a
2:10
small project or a large scale
2:12
application,
2:13
React has the tools you need to succeed.

💡 Learning React is not just about coding—it’s about understanding a new way to build web apps. Once you know the fundamentals, you can move on to advanced topics like hooks, performance optimization, server-side rendering, and full-stack development with Next.js.
