How to Compose React Components in React

In this code we nest the components NonCitrus and Citrus into the Fruits Component.

Then nest the Fruits within the TypesOfFood component. 

Also added the additional components, Vegetables, NonCitrus and Citrus so that the code is complete. 

HTML

<div id="root"></div>

For a long time it had seemed to me that life was about to begin - real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, or a debt to be paid. Then life would begin. At last it dawned on me that these obstacles were my life.
