 Creating components inside components without memoization leads to unstable components. The nested component and all its children are recreated during each re-render. Given stateful children of the nested component will lose their state on each re-render.
 
-React reconcilation performs element type comparison with [reference equality](https://github.com/facebook/react/blob/v16.13.1/packages/react-reconciler/src/ReactChildFiber.js#L407). The reference to the same element changes on each re-render when defining components inside the render block. This leads to complete recreation of the current node and all its children. As a result the virtual DOM has to do extra unnecessary work and [possible bugs are introduced](https://codepen.io/ariperkkio/pen/vYLodLB).
