React 19 and it's features

# What's New in React 19?

React 19 is the latest version of the popular JavaScript library for building user interfaces. It comes with several exciting new features and improvements that make development easier and more efficient. Let's dive into what's new in React 19:

# Key Features

1. React Compiler

React 19 introduces a new compiler that optimizes your code for better performance. This compiler helps reduce the size of your JavaScript bundles, making your applications load faster.

2. Server Components

Server components allow you to render parts of your application on the server, reducing the amount of JavaScript that needs to be sent to the client. This results in faster load times and improved performance.

3. Actions

Actions are a new way to interact with DOM elements in React. They simplify the process of handling user interactions and make your code more readable and maintainable.

4. Web Components

React 19 now supports web components, allowing you to use custom elements in your React applications. This opens up new possibilities for reusing and sharing components across different projects.

5. Document Metadata

With React 19, you can now manage document metadata more efficiently. This feature helps you set and update metadata like titles, descriptions, and keywords, improving your application's SEO.

6. Asset Loading

React 19 introduces a new way to load assets in the background, improving your application's load time and user experience.

7. Enhanced Hooks

React 19 comes with several new hooks that make it easier to manage state and side effects in your components. Some of the new hooks include `use()`, `useFormStatus()`, `useFormState()`, and `useOptimistic()`.
