React Concurrent Mode is an experimental feature that provides a more fluid user experience. It enables React to interrupt the rendering process and switch to tasks that have higher priority when needed, such as handling user input or maintaining animations to prevent visual lag.
Concurrent Mode splits the rendering process into small chunks, making the application more responsive. It also allows you to opt-in and decide which components need instant visual feedback.
This mode can also be used to load components progressively, similar to how images progressively load, providing a smoother user experience, as users can start interacting with parts of the UI that are already rendered while the rest continues loading in the background.
