General information about Javascript, Java and Flash


The fakoo.de site uses only the browser's Javascript for the interactivity of the learning and information pages.

This programming language runs directly in the user's browser and is therefore very fast. And the program code is open and easy to adapt. But since there are always concerns about Javascript, here is a comparison with Java and Flash.


The difference between Java and Javascript

Despite the similar name, Java and Javascript have as much in common as car and cartridge.

Comparison Javascript Java
Type Scripting language for browsers complete programming language
require­ments modern browser (Javascript enabled) Software Java Virtual Machine
+ plugin for browser (for use online)
Use Evaluation of mouse movement, form control, interaction with users, use of cookies, changing website content and adapting appearance
Almost all providers use Javascript to improve their offer, since it runs directly in the user's browser.

Javascript makes it possible for HTML pages to interact without having to request or change the entire page with new content.

However, the strength of Java lies outside of the Internet in platform-independent computer applications.

The biggest use of Java today is in programming apps for Android phones.

In addition to Java, website applications were also offered in Flash. Flash was safer and easier to use, but had the disadvantage that the entire application had to be loaded first. Flash was discontinued in 2020.
transmission within HTML files or as separate JS file as applets in separate CLASS files
Call in HTML <script>... </script> <applet>... </applet>
Code Script statements (readable) Applets are precompiled (unreadable)
Security Javascript has access only to browser objects, special actions require explicit permission of user (browser settings)

Unfortunately, Javascript can only be activated or deactivated in Internet Explorer together with VBScript. And VBScript is a programming language that also has write and read access to files on the computer. Therefore, VBScript is a security risk.

Applets are complete program codes that are executed on the user's computer. The browser plugin provides a separate runtime environment (sandbox). A security risk from "malicious" applets only exists if the sandbox is faulty (bytecode control).
(Tip: Only load applets from signed sources)
Notes to programmers Websites must also remain functional without Javascript. For technical reasons it is often not possible for the user to use Javascript.

„Bad style“ includes:

  • „Obfuscate“ source code to hide it from prying eyes
  • Disable the context menu to prevent images or the entire page from being saved
  • Disable the copy function to prevent text or images from being copied
  • Unsolicited (advertising) pop-ups or pop-unders (although most modern browsers have pop-up blockers, these can be circumvented with a few tricks)
 Check if the user can use Java by placing a Java-based link to Java offerings.

Java is off in your browser!

Just checking whether Java is switched on via Javascript does not mean that the Java browser plugin is installed.

AJAX AJAX connects JavaScript in the browser with server functions.
This enables functions in a page that would normally require a page refresh - for example, searching a database while typing in a form (every keystroke is sent to the server).

AJAX-Functions cannot be made barrier-free because the content of a page changes dynamically. The saving of favorites (linking of the content) and the navigation in the browser are also limited.

No AJAX is used on fakoo.de, all data are already contained in Javascript files or are available as HTML files or text and can be linked directly.

Only install Java VM (Java Virtual Machine) if you absolutely need Java. There are hardly any websites that use Java anymore.

Javascript , on the other hand, can be switched on safely if you are using a current browser in the current version. Javascript is enabled by default in the browser..

When you scrolling back in the browser, the corresponding pages are loaded from the browser's cache. Therefore, these pages must always also be updated afterwards!
