## JSX

* JSX stands for JavaScript XML.
* It allows writing HTML in JavaScript and converts the HTML tags into React elements.
* Capitalized types indicate that the JSX tag is referring to a React component. \
  These tags get compiled into a direct reference to the named variable, so if you use the JSX `<Foo />` expression, `Foo` must be in scope.
