A basic unit of JSX is called a JSX element.

Here’s an example of a JSX element:

<h1>Hello world</h1>

This JSX element looks exactly like HTML! The only noticeable difference is that you would find it in a JavaScript file, instead of in an HTML file.

In app.js, write a JSX <p></p> element containing the text, Hello world. Use the example code above as a guide.
