<h1>Übung 46: Richtige Gewinner</h1>
|
|
<p>
|
|
Die Ausgabe der Gewinner aus dem letzten Beispiel (Codebeispiel 324) ist immer noch nicht ideal. Am Besten
|
|
wäre das folgende Ergebnis-Array:
|
|
</p>
|
|
<pre>
|
|
<code>
|
|
[
|
|
'1st place: Heribert',
|
|
'2nd place: Friedlinde',
|
|
'3rd place: Tusnelda',
|
|
'Oswine',
|
|
'Ladislaus',
|
|
]
|
|
</code>
|
|
</pre>
|
|
</div>
|
|
<div class="output alert alert-secondary"></div>
|

</div>
|

<script>

'use strict';

const outputEl = document.querySelector('.output');
|
|
|
|
const winners = ['Heribert', 'Friedlinde', 'Tusnelda', 'Oswine', 'Ladislaus'];
|
|
|
|
// const PlaceWinner = () => {

const getWinners = (winners) => {

if (i === 0) {
