This update introduces several significant improvements to application performance and rendering. One of the most notable features is "Concurrent Mode", which allows applications in React to be more responsive and fluid by taking advantage of idle time on the main browser thread to run secondary tasks. This results in a faster and smoother user experience, especially in interaction-intensive applications.
In addition, it implements "Update Batching" by default, which means that state updates are batched and processed in batches, resulting in fewer rendering operations and thus improved performance.
With React 18, developers have greater control over the granularity of component updates. The introduction of "React Server Components" allows components to be rendered on the server and sent to the client, which significantly improves initial load speed and optimization for search engines.
In addition, it allows selective updating of components through the use of "Partial Updates", which means that only the components that have changed are rendered and updated, rather than re-rendering the entire UI. This results in time and resource savings, which translates into greater development efficiency and a better user experience.
Gradual adoption: React 18 is designed to allow gradual adoption, which means that you can start using the new React features in specific parts of your application, without the need to update the entire project right away. This is useful if you have an existing code base and want to migrate incrementally.
Greater focus on the community: There is a greater focus on developer community participation and collaboration. This translates into greater transparency in the decision-making process, feedback gathering, and issue resolution. The React community is active and diverse, which means there are always opportunities to learn and contribute.
Cross-platform support: Extends its support beyond traditional web applications. You can now use React to build native mobile apps, desktop apps, and even virtual and augmented reality experiences. This increases development possibilities and allows you to create applications on different platforms using the same skills and tools.
Debugging enhancements: Brings improvements to the debugging tools, making it easier to identify and fix problems in your applications. Improvements include more descriptive error messages, better warnings, and a better ability to track and understand the flow of data in the application.
Future experiments and features: With React 18, several future experiments and features will also be introduced and are being developed in parallel. These features are not yet ready for production use, but provide an exciting glimpse into the future possibilities of React. Examples of these experiments include work on "React Server Streaming" and "React Fast Refresh".
