Explanation of React Fiber
Introduction React Fiber is the core reconciliation engine of React supported since version 16, helping to change the rendering mechanism from synchronous to asynchronous. Advantages: Ability to pause and resume work: Allows React to break the rendering process into small units of work (fibers) so as not to block the main thread. Task prioritization: Prioritizes direct user interactions (keystrokes, clicks) over background data processing tasks. UX Improvement: Minimizes lag (jank) when the application has to handle complex UI components or large data lists. Detailed Workflow React Rendering Pipeline Trigger Phase When you call setState() or dispatchAction, React marks the changed nodes as dirty and uses the lane mechanism to mark upwards to the corresponding parent Fiber Nodes. Fiber: Acts as a "unit of work." Each component is a Fiber node containing information about state, props and links to parent/child/sibling nodes.
