Le applets Java es appellate de archivos HTML.

   <html>   <head>   <title>Hallo Mundo</title>   </head>   <body>

Mi programma "hello world" dice:

   <applet code="HalloMundo.class" width="600" height="100">   </applet>   </body>   </html>

   import java.applet.*;   import java.awt.*;

   public class HalloMundo extends Applet {     public void paint(Graphics g) {       g.drawString("Hello, world!", 100, 50);     }   }

JavaScript (o ECMAScript) es un linguage de programmation de scripts incastrate in files HTML. Pro probar iste programma simplemente pone le codice sequente intra le elemento <head> de qualcunque file HTML.

    <script language="javascript">    function halloMundo()    {        alert("Hello, world!");    }    </script>

    <a href="javascript:this.location()"     onclick="javascript:halloMundo();">Programma "hello world"</a>

Un methodo plus facile usa le JavaScript in un maniera implicite, e appella le function reservate alert. Copia e colla le sequente codice intro le elemento <body> de un file HTML.

    <a href="#" onclick="alert('Hello, world!')">Programma "hello world"</a>

Un methodo ja plus facile usa le protocollo virtual 'javascript' (supportate per le majoritate de navigatores popular) pro executar le codice. Simplemente pone le linea sequente a in le campo de adresse de vostre navigator:

    javascript:alert('Hello, world!')

   <window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">   <box align="center">   <label value="Hello, world!" />   </box>   </window>

Le serie sequente de characteres (exprimite ci in notation hexadecimal):

    48 65 6C 6C 6F 2C 20 77 6F 72 6C 64 21 0D 0A

   <html>   <head>   <title>Hallo, Mundo!</title>   </head>   <body>   <p>Hello, world!</p>   </body>   </html>
