How does react reduce the number of re-renders?
This is why React uses reconciliation to efficiently determine which elements need to be updated on the DOM and re-rendered, which vastly reduces the number of times the DOM needs to be read from and written to. React also has other optimization techniques such as batching multiple state updates into a single update to prevent multiple re-renders.
