VSSD - Java and Javascript

The difference between Java and JavaScript

Java is not JavaScript
JavaScript is not Java

JavaScript is a scripting language developed by Netscape and has no relation to Java (it was originally supposed to be called LiveScript, but with the advent of Java, the term JavaScript sounded nicer...). Java and JavaScript are different.

Java, developed under the Sun Microsystems brand, is a full-fledged object-oriented programming language. It can be used to create standalone applications and a special type of mini application, called an applet. Applets are downloaded as separate files to your browser alongside an HTML document, and provide an infinite variety of added functionality to the Web site you are visiting. The displayed results of applets can appear to be embedded in an HTML page (e.g., the scrolling banner message that is so common on Java-enhanced sites), but the Java code arrives as a separate file. Java is really for fully fledged programmers.

JavaScript, developed by Netscape, is a smaller language that does not create applets or standalone applications. In its most common form today, JavaScript resides inside HTML documents, and can provide levels of interactivity far beyond typically flat HTML pages -- without the need for server-based CGI (Common Gateway Interface) programs.
