React

• Component What kind of JavaScript value does React actually accept as a renderable description?
• Renderer How does that description become a real DOM node?
• JSX If React wants element objects, what exactly is JSX syntax doing?
• Props If a component is just a type in an element, how does data get into it?
• Events If UI descriptions are static values, how does user interaction enter the system?
• State If props come from outside, where does changing local data live?
