A component that takes props as an argument and returns the element to render.
These components behave just like a React class with only a render method defined.
Since no component instance is created for a functional component, any ref added to one will evaluate to null.
Functional components do not have lifecycle methods.
"In the future, we’ll also be able to make performance optimizations specific to these components by avoiding
unnecessary checks and memory allocations."
