JavaScript - Trivia & Facts

- As of 2009, the latest version of the language is JavaScript 1.8.1. However, not all browsers support the latest version (as there is no specific need). IE 8 supports JScript 6 (which is equivalent to ECMAScript 3, JavaScript 1.5 - more bug fixes over JScript 5) while Firefox 3.0 supports JavaScript 1.8 (1.7 + Generator Expressions + Expression Closures + misc.)

Check this test page & it's source to know which browser supports which version.

- JavaScript was originally developed by Brendan Eich of Netscape under the name Mocha, which was later renamed to LiveScript, and finally to JavaScript

- JavaScript, despite the name, is essentially unrelated to the Java programming language even though the two do have superficial similarities. 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" is a trademark of Sun Microsystems

- JavaScript is officially managed by Mozilla

- Microsoft's compatible dialect of the language is JScript.

- Owing to the popularity of the World Wide Web, JavaScript is the lingua franca of the Web and is possibly the most used programming language.
