-Although render trees may differ across render pases, these trees are generally helpful for identifying what the *top-level* and *leaf components* are in a React app. Top-level components are the components nearest to the root component and affect the rendering performance of all the components beneath them and often contain the most complexity. Leaf components are near the bottom of the tree and have no child components and are often frequently re-rendered.
