What is JSX?


In this section, we'll implement the obligatory hello world JSX application. At this point, we're just dipping our toes into the water; more in-depth examples will follow. We'll also discuss what makes this syntax work well for declarative UI structures.

Hello JSX

Without further ado, here's your first JSX application:

// The "render()" function will render JSX markup and 
// place the resulting content into a DOM node. The "React"
