Daz Script 2 is a dynamically-typed, interpreted, object-oriented scripting language that is tightly integrated with the Daz Studio API. It is an extension of Qt Script, which is an extension of ECMAScript as defined in the ECMAScript Language Specification (ECMA-262), 5.1 Edition.

Syntactically Daz Script is very similar to JavaScript, JScript, and ActionScript. If you have any familiarity with these languages, chances are you will find the transition to Daz Script quite comfortable. However, it may be a little unintuitive at first for developers more familiar with strongly typed, compiled languages.

Daz Script 1 was based on QSA (Qt Script for Applications), which derived from the ECMA-262 3rd edition standard and the 4th edition proposal. In QSA, most of the run-time logic, such as classes and scoping rules, were based on the 4th edition proposal, while the library implementation was based on the 3rd edition standard. The 4th edition proposal ended up not being accepted¹⁾. So, in Qt 4.5²⁾, Trolltech decided to end-of-life the QSA product and develop a new native scripting engine based on JavaScriptCore, that was compliant with the 3rd edition standard, and Qt Script was born. As a result of these events it became essential that we adapt, so Daz Script 2 finds its roots amidst the efforts of Qt Script compliance with the ECMA-262 standard.

Information related to porting QSA based scripts to being Qt Script based can be found in the Moving from QSA to Qt Script document.
