**01 :  The React Compiler**
At the forefront of React 19 is the eagerly awaited React Compiler, a revolutionary tool that redefines how React applications are built and optimized. By converting React
code into optimized JavaScript during the build process,
the React Compiler holds the potential to double
performance, significantly improving the efficiency and
responsiveness of applications. With the React Compiler,
developers can unlock unparalleled performance gains
without sacrificing development speed or productivity.

**02 : Actions**
React 19 introduces Actions, a powerful abstraction that
simplifies data handling and interactions within web pages.
With Actions, developers can encapsulate complex logic
into reusable units, promoting modularity and
maintainability. By decoupling UI components from data
manipulation, Actions streamline development workflows
and empower developers to create more dynamic and
interactive user experiences with ease.

**03 : Server Components**
In a bid to enhance performance and SEO, React 19
introduces Server Components, a game-changing feature that

enables components to be rendered on the server. By pre-
rendering components on the server, React 19 accelerates

page loads, delivering faster rendering times and improved
search engine visibility. Server Components represent a
significant advancement in React development, offering
developers a powerful tool to optimize performance and
enhance the discoverability of their applications.

**04 : Asset Loading**
React 19 introduces seamless asset loading, allowing
assets such as images, stylesheets, and scripts to be
loaded in the background. By preloading assets, React 19
minimizes latency and enables smoother page transitions,
enhancing the overall user experience. With asset loading,
developers can ensure that their applications feel
responsive and fluid, even in bandwidth-constrained
environments.

**05 : Document Metadata**
Enhancing the discoverability of web applications is made
easier with React 19's Document Metadata feature. By
leveraging the <DocumentHead> component, developers can
effortlessly manage document metadata, including title tags,
meta descriptions, and canonical URLs. This streamlined
approach to SEO optimization enables developers to enhance
the visibility and relevance of their applications in search
engine results, driving organic traffic and engagement.

**06 : Web Components**
React 19 extends its support for Web Components,
offering improved compatibility and interoperability for
more flexible development. By seamlessly integrating with
existing Web Components, React 19 empowers
developers to leverage the rich ecosystem of reusable UI
elements, libraries, and frameworks, enabling faster
development cycles and greater code reusability.

**07 : Enhanced Hooks**
Building upon the success of React Hooks, React 19
introduces Enhanced Hooks, providing developers with
greater control over component lifecycle and state
management. With Enhanced Hooks, developers can finetune the behavior of components, optimize performance,
and build more scalable and maintainable applications.
Whether it's managing side effects, handling asynchronous
operations, or orchestrating complex state transitions,
Enhanced Hooks offer a powerful mechanism for building
robust and efficient React applications.
