This chapter will introduce you to JSX. We'll start by covering the basics: what is JSX? Then, you'll see that JSX has built-in support for HTML tags, as you would expect, so we'll run through a few examples here. After having looked at some JSX code, we'll discuss how it makes describing the structure of UIs easy for us. Then, we'll jump into building our own JSX elements, and using JavaScript expressions for dynamic content. Finally, you'll learn how to use fragments to produce less HTML—a new React 16 feature.
