-JSX makes code that deeply nests React components more readable, and writing it
-feels like writing HTML. React documentation examples make use of JSX.

 ## Why JSX?
 
-First of all, **don't use JSX if you don't like it!** All of React's features
-work just fine without using JSX. Simply construct your markup using the functions
-on `React.DOM`. For example, here's how to construct a simple link:
