Tamarin Project. Goals The goal of the "Tamarin" project is to implement a high-performance, open source implementation of the ECMAScript 4th edition (ES4) language specification.
The Tamarin virtual machine will be used by Mozilla within SpiderMonkey, the core JavaScript engine embedded in Firefox®, and other products based on Mozilla technology. The code will continue to be used by Adobe as part of the ActionScript™ Virtual Machine within Adobe® Flash® Player. The Tamarin virtual machine currently implements the ECMAScript 3rd edition language standard that is the basis for JavaScript, Adobe ActionScript, and Microsoft Jscript, plus some of the new language features proposed in the ECMAScript 4th edition specification.

JavaScript - MDC. A re-introduction to JavaScript - MDC. Why a re-introduction?
Because JavaScript is notorious for being the world's most misunderstood programming language. It is often derided as being a toy, but beneath its layer of deceptive simplicity, powerful language features await. JavaScript is now used by an incredible number of high-profile applications, showing that deeper knowledge of this technology is an important skill for any web or mobile developer. It's useful to start with an overview of the language's history.
