- Java
- An object-oriented programming language developed by Sun Microsystems and designed to be small, simple, and portable across platforms and operating systems. It is best known for its 'applets,' dynamic, interactive programs that can run inside a World Wide Web page displayed by a Java-capable browser. The origins of the name 'Java' are explained as:'it survived the trademark search.'
- JavaScript
- A scripting language developed by Netscape to enable Web authors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently. JavaScript can interact with HTML source code, enabling Web authors to add dynamic content to their sites. It is supported by most browsers, although Internet Explorer supports only a subset, which Microsoft calls Jscript.
