map()

I think the map() method returns a new array. If so, how the code below works?

{props.initialPlayers.map( player => <Player name={player.name} score={player.score} key={player.id.toString()}/> )}

It returns an array with each array item containing a piece of JSX. When this is transpiled (converted to HTML and JavaScript) by Babel, it will appear as a set of HTML elements.
