React enhances application performance through batching state updates and scheduling rendering tasks. Batching allows multiple updates to be processed in a single render pass, which reduces render frequency. Scheduling ensures that high-priority tasks, such as user interactions, are handled first. Prior to React 18, batching was limited; however, with the advent of Concurrent Mode and React Fiber architecture, functionalities like pausing and resuming updates have been integrated. This advancement is vital for creating smooth user interfaces and improves responsiveness in real-world applications.
React allows multiple updates to be batched together, which minimizes the number of render passes and significantly improves performance in applications. With this optimization, developers can create smoother and more efficient user interfaces by reducing the number of times components are rendered.
The introduction of Concurrent Mode in React 18 enables better scheduling of render tasks, allowing more urgent updates, such as user inputs, to be prioritized over less critical tasks. This leads to a more responsive user experience.
