Web Programming Languages: JavaScript, Java

JavaScript is not Java
JavaScript and Java are popular web programming languages that are often a point of confusion. Most think that JavaScript is the same as Java or it is a version of Java programming. However, despite their names, JavaScript and Java are different programming languages. So, let us clear up Java and JavaScript difference.

JavaScript Is NOT Java

javascript-vs-java
The common misconception is caused with the prefix -Java. However, JavaScript is not Java and not related to Java technology. The strategy behind choosing JavaScript as a final name probably has to do with marketing.

Wikipedia:

JavaScript was originally developed by Brendan Eich of Netscape under the name Mocha, which was later renamed to LiveScript, and finally to JavaScript. LiveScript was the official name for the language when it first shipped in beta releases of Netscape Navigator 2.0 in September 1995, but it was renamed JavaScript in a joint announcement with Sun Microsystems on December 4, 1995 when it was deployed in the Netscape browser version 2.0B3.

The change of name from LiveScript to JavaScript roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser. The final choice of name caused confusion, giving the impression that the language was a spin-off of the Java programming language, and the choice has been characterized by many as a marketing ploy by Netscape to give JavaScript the cachet of what was then the hot new web-programming language. It has also been claimed that the language's name is the result of a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun's Java runtime with their then-dominant browser.

JavaScript & Java Difference


JavaScript was developed at Netscape. Java was developed at Sun Microsystems. The JavaScript was originally called Mocha and LiveScript. Java was originally called Oak. JavaScript syntax was influenced by programming language C. Java syntax comes from C and C++.

Although both have similarities, JavaScript is not Java. The JavaScript principles are taken from web programming languages the Self and Scheme. JavaScript is an interpreted computer programming language implemented as part of web browsers.
JavaScript is a cross-platform, object-oriented scripting language. JavaScript is a small, lightweight language; it is not useful as a standalone language, but is designed for easy embedding in other products and applications, such as web browsers. JavaScript and Java are similar in some ways but fundamentally different in some others. The JavaScript language resembles Java but does not have Java's static typing and strong type checking. JavaScript follows most Java expression syntax, naming conventions and basic control-flow constructs which was the reason why it was renamed from LiveScript to JavaScript. (source find more info on JavaScript vs Java differences in Details of the Object Model)

Java is a general-purpose, class-based, object-oriented programming language. Javascript is used for front-end web development. Java can only be used as a back-end language. JavaScript is a scripting language and programming code that can be inserted into HTML and executed by all modern web browsers. Java doesn’t need a web browser to compile and execute like Javascript. Java creates applications that run in a virtual machine or browser while JavaScript runs only in a web browser. Java code needs to be compiled while JavaScript code is all in text. JavaScript and Java have different plug-ins. JavaScript is dynamic and weakly typed. Java has static typing and is strongly typed. Java is loaded from compiled bytecode. JavaScript is loaded as human-readable source code. Java is class-based. JavaScript is prototype-based.

JavaScript vs Java difference lies in the technology. JavaScript and Java are different web programming languages. JavaScript is not Java.

Javascript Programming

One more widely used programming language in the modern web application design and development is Javascript. The main purpose behind the JavaScript programming is making web applications more interactive and responsive, subsequently providing the users with a much better user experience.

What is JavaScript 

Javascript is a client-side language with processing engine embedded in web browsers. JavaScript programming was originally invented as part of web browsers. As a client-side language, JS allows users to interact with web pages and load the content without refreshing the web page.

Originally, JavaScript was developed in Netscape under the name LiveScript. The choice of “JavaScript” name caused a misconception that the language is a version of the programming language known as JAVA. However, although both have some common syntax, JavaScript and Java are different languages. JavaScript was developed at Netscape, while Java was originally developed at Sun Microsystems. The syntax of JavaScript was influenced by one more widely used programming language C. JavaScript is a multi-paradigm, prototype-based, object-oriented, imperative, and functional scripting language, not a real programming language.

Google Chrome extensions, Opera's extensions, Google Desktop Gadgets, Apple's Safari 5 extensions are implemented using JavaScript. Outside of web browsers and web pages, JavaScript are be used in PDF files as well as for desktop application creation.

JavaScript Features

Javascript brings more dynamic functions and features to HTML. The most common use of JavaScript is writing functions that are embedded in HTML and interact with the Document Object Model. Let us look at just some JavaScript programming features:

 • Loading the content via AJAX without reloading the web page
 • Manipulating, moving, resizing, etc web page elements, animation, visual effects
 • Interactive content using and developing, game development, audio/video
 • Performing web form validations, as well as calculations
 • Other

The latest version is JavaScript 1.8.5. jQuery and Prototype are popular JavaScript libraries. The development of Ajax enhanced the interest to JavaScript language using and implementation.
