React Fiber is a re-write of React’s core algorithm which aims in improved rendering and responsiveness of the UI. React Fiber helps in improving performance of UI intensive operations like animation, layouts etc. React Fiber improves the algorithm to render / re-render changes to the DOM thereby improving the performance / UI responsiveness of React applications.
