A web application is presented by defining a structural DOM to be rendered.
93+
When the state of the application changes, perhaps due to a user event, the DOM
94+
structure changes to represent the new state. React.js divides up the DOM rendering
95+
and interactivity into components with each component being responsible for its own
96+
state and presentation.
