JavaScript Reference
This chapter lists and describes JavaScript classes, objects, methods, attributes, and global functions defined by
After Effects.
The After Effects scripting engine supports ExtendScript, Adobe's extended version of JavaScript, which imple-
ments the 3rd Edition of the ECMA-262 Standard, including its notational and lexical conventions, types,
objects, expressions and statements. For a complete listing of the keywords and operators included with
ECMAScript, refer to , available at

The After Effects Object Model
As you look through this reference section, which is organized alphabetically by object, you can refer to the
following diagrams for an overview of where the various objects fall within the hierarchy, and their correspon-
dence to the user interface.
Hierarchy diagram of the main After Effects scripting objects
Note that the File, Folder, and Socket objects are defined by ExtendScript, and are documented in the JavaS-
cript Tools Guide. ExtendScript also defines the ScriptUI module, a set of window and user-interface control
objects, which are available to After Effects scripts. These are also documented in the JavaScript Tools Guide.
The hierarchy of objects in scripting corresponds to the hierarchy in the user interface.
