• Quick Summary React v18.0 has been released!
  Its been two months since the last major
  release, so what can we expect from this new
  version of React? As expected, React 18 features
  new server rendering capabilities, Hooks, and
  React Elements. These are exciting changes that
  will help developers create user experiences that
  are faster than ever before.
• In summary, it will pose a significant challenge
  to the TezJS framework, which is also responsible
  for the construction of UI components.

React is Design Oriented

• React 18 delivers the new React Shallow
  Rendering. It lets you declaratively render tree
  fragments without having to worry about what
  happens when the data changes. That frees you up
  to focus on writing React components that produce
  the output for their parent nodes, instead of
  handling the details of every possible change.
• React v18 is the newest addition to the React
  family. It has an amazing UI focus that catches
  the attention of designers and development teams.
  Therefore, they embrace React v18, highlight it
  in their presentation, and actively collaborate
  with designers and other UI/UX specialists to
  improve the library.

What is React 18 Concurrent Mode?

• Concurrent is the most important feature of React
  v18.0.0 that has enabled people to use React
  without worrying about the performance issues
  related to the significant memory consumption of
  the new version. Concurrent is a background task
  in React, which does not mess with your UI
  components. All it basically does is that it
  create a separate instance for the DOM nodes
  instead of creating multiple versions of a single
  node. This enables you to save the memory
  significantly without worrying about performance
  issues like before.

• React has organized itself as one of the best
  solutions to achieve a modern user experience. It
  has made it simple for developers to build
  amazing applications that offer a seamless user
  experience. Its intuitive features make it highly
  flexible to fit into any kind of application.
  This has made React developers highly sought
  after in the industry.
• React rendering is a process of undertaking UI
  updates in an interval. Imagine you are adding
  some text to your page, as soon as you touch the
  Keyboard, React scrolls everything behind the
  text and omits the previous content in front.
  This is what react does it maintains the
  consistency in UI irrespective of unplanned
  interruptions.

6

• So, youve heard that theres a new version of
  React. The big news is React Fiber, and the
  ability to pre-cache rendering for smooth
  transitions. But another change is the
  introduction of ltOffscreengt, which brings
  react-routers ltRedirectgt method to everyone.
  Its a flexible way to create a seamless
  transition between two screens, in the same tab
  or a different tab.

7
New Suspense Features

• The goal of react-suspense is to help developers
  transition from code that uses dynamic imports
  today (code that does not take advantage of
  Reacts dynamic import feature) to code that uses
  them in the future. This will make it easier for
  developers to update their components to use
  Suspense when it is released. The react-suspense
  package was created by Michael Jackson as part of
  the Facebook React teams work on Suspense, which
  is part of their ongoing effort to make rendering
  asynchronous and non-blocking by default.

8

• React Server Side Rendering is a process where we
  can execute ReactJS code on the server side. This
  process allows us to enhance our user experience
  by giving them content faster. It also helps
  search engines crawl your website quicker and
  easier. Re-rendering the whole page would ensure
  up-to-date content being rendered for search
  engine indexing.
• One of the major changes that React version 18
  brings is the way it handles suspense. However,
  in the migration process to React version 18, we
  would need to make very few changes to our code
  so as to keep everything working (or close to
  working) as before.

9
Streaming Server Rendering

• In React 18, this situation is improved.
  Server-side rendering now allows for incremental
  updates components will render asynchronously to
  state changes, and when all of the components
  have been rendered, an update callback can be
  invoked to re-render the main page. By
  re-rendering as few components as possible once
  JavaScript is available, server-side rendering
  ensures a smoother experience for your users,
  even in complex applications with many slow
  components.

10

• React Suspense was introduced in React v.18. It
  allows us to load components asynchronously. With
  this library, we can pause rendering by wrapping
  our (Suspense) tag around an async component and
  the component will not be loaded until its
  ready. This means you can load an image, video,
  or even a component after everything else has
  already been rendered on the screen. Further, we
  can show a loading animation for any UI elements
  that are yet to be seen by the user.

11
Automatic Batching

• Batching is an integral part of React apps and
  components for grouping state updates with the
  help of inbuilt hooks and event handlers. This
  will help prevent components from re-rendering
  for all state modifications unnecessarily,
  resulting in improved overall speed (and
  performance) of a component. If you have been
  using React, you know that this wasnt possible
  until the release of React 17. But with the
  latest version React 18 the framework has
  added support for automatic batching, enabling
  you to improve performance even further.

12

• Allows you to batch state updates from
  createRoot. This includes native event handlers,
  asynchronous operations, and intervals. Makes use
  of bulk and partial requests to reduce the number
  of calls on the server. Makes integration with
  Restler support tokens ultra-easy.

13
Stopping Automatic Batching with flushSync()

• React 18 comes with a new method called
  ReactDOM.flushSync() that helps in synchronizing
  an arbitrary number of React updates to build
  output and DOM response at the same time.
  However, for this method to work, it requires
  that any code in your app must not read anything
  straight from the DOM during an update. In other
  words, if you are using refs, event handlers,
  browsers, or libraries that read the scroll
  position, dimensions, or other things straight
  from the DOM then you need to disable automatic
  batching first by calling setAutoBatching(false)
  before calling flushSync().

14
Transition

• React recently introduced a new concept called
  Transition to allow the application to prioritize
  updates that the developer expects consumers to
  interact with more frequently. The developer can
  specify how long an update should take in
  real-world time to trigger this transition. These
  urgent updates that intersect with the transition
  are prioritized ahead of others when the updates
  occur. Transition was added to React to aid
  developers who want to emphasize user experience
  within applications. Especially, its useful when
  incorporating dynamic or content-based components
  into an application such as news feeds.

15
New Client and Server Rendering APIs

• React 18 has redesigned the APIs to render on the
  client and server sides. Now, all users can
  continue utilizing the old React 17 APIs while
  upgrading to the new React 18 APIs. This gives us
  the opportunity to have new features added to the
  mix. Thanks to the Webpack 4 update, we can be
  confident that our bundle size will go down
  significantly.

16
New Strict Mode Behaviors

• Strict mode was introduced to the React community
  in the 16.3 version. It helps to identify the
  code patterns that could impact the performance
  of concurrent rendering APIs and displays error
  messages or code suggestions to help developers
  improve their code

17
New Hooks

• React Hooks are the newest trending topic in the
  world of JavaScript frameworks. React developers
  and UI designers have been waiting a long time to
  get this update. In fact, Facebook itself has
  been working on developing the hooks for 10
  months. The primary concept behind the update is
  that it was introduced because of the functional
  components used by React. In their words, they
  wanted to provide more options for developers to
  write software. Moreover, they wanted to give
  developers more control over the code needed to
  accomplish things like animations or state
  management.

18
Conclusion

• React 18 brings a host of game-changing features
  and enhancements to the table, revolutionizing
  the development experience, boosting performance,
  and unlocking new horizons for crafting
  cutting-edge web applications. With Concurrent
  Mode, concurrent rendering takes center stage,
  resulting in a highly responsive user interface.
  Meanwhile, React Server Components act as a vital
  link between server-side and client-side
  rendering, paving the way for performance
  optimization and decreased client-side processing.
