<h2>💡 1. Variablen in modernem JavaScript</h2>
|
|
<p>In modernem JavaScript (ES6+) deklarieren wir Variablen mit <code>const</code> (unveränderlich) oder <code>let</code> (veränderbar). Das alte <code>var</code> sollte vermieden werden.</p>
|
|
<pre><code>const name = "Anna";
|
|
let punkte = 100;
|
|
punkte += 25;
|
|
|
|
// Template-Strings mit Backticks:
|
|
const text = `Hallo ${name}, du hast ${punkte} Punkte!`;
|
|
console.log(text);</code></pre>
