What is a Stateless Functional Component in React

What is a Stateless Functional Component?

A stateless component is one that can recive data and render it, but it does not manage the provided data or track changes to it. 

This method creates a javascript function that returns JSX or null. Which is also known as a component or JSX component (or a react component?).

React also requires that you start the function name with a Capital Letter, which seems very picky. 

So you cant have a function called myFunction it has to be called MyFunction.

When testing this i could not get it to render properly, as i think you have to call the function within < and > according to this document

so rather than this to render the MyComponent function

ReactDOM.render(MyComponent, document.getElementById('root')) 

it becomes this

ReactDOM.render(<MyComponent />, document.getElementById('root'))

just testing this using the react browser tools, and it registers as a component!

HTML

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