react components
React puts interactivity first
Traditional html pages put html first and sprinkle in js as a secondary interactivity
React flips this concept - a React component is a JavaScript function that you can sprinkle with markup

export default function Profile() {
return <img src="https://i.imgur.com/MK3eW3Am.jpg" alt="Katherine Johnson" />;
}
Return statements
Return statements can be written all on one line, as in this component:
1
return <img src="https://i.imgur.com/MK3eW3As.jpg" alt="Katherine Johnson" />;
if your markup isn’t all on the same line as the return keyword, you must wrap it in a pair of parentheses:
1

return (
<div>
<img src="https://i.imgur.com/MK3eW3As.jpg" alt="Katherine Johnson" />
</div>
);
