Render Props in Stencil

Before I started to use Stencil, I worked a lot with React (and am still working with the library). While developing React components, you often need to use a render prop, so I wanted to see how it would work in a Stencil environment. As you might figure, it works in Stencil and this gave me the idea to write a short post to explain how to use the render prop in Stencil.
Render Prop
A render prop is just a name for a simple technique in which you pass a function to a component which will be used in the component render function. The reason to use a render prop is the ability for a component to share its inner state without exposing it to the outside.
