952 PointsWhy declare a variable for the total number of players instead of putting the data inline?
Why this:
const Stats = (props) => {
const totalPlayers = props.players.length;
return (
<table className="stats">
<tbody>
<tr>
<td>Players:</td>
<td>{totalPlayers}</td>
</tr>
<tr>
<td>Total Points:</td>
<td>{props.score}</td>
</tr>
</tbody>
</table>
);
};
Instead of this:
const Stats = (props) => {
return (
<table className="stats">
<tbody>
<tr>
<td>Players:</td>
<td>{props.players.length}</td>
</tr>
<tr>
<td>Total Points:</td>
<td>{props.score}</td>
</tr>
</tbody>
</table>
);
};
Is this just a stylistic choice or is there a practical reason? They seem to work the same.

Treehouse TeacherHey Seth wright !
You're correct, both will work just fine. I think that the top option makes the JSX more readable and if you were to need to access props.players.length
again, it would save you from needing to type all of that out multiple times.
