Introduction

This chapter lists and describes all syntax (keywords, statements, operators,classes, objects, methods, attributes, and global functions) recognized by the After Effects scripting engine.

Note that in ECMAScript and JavaScript, a named piece of data of a certain type is commonly referred to as a property. However, in After Effects we already have a separate definition of a "property" : it is a specific editable value within a layer. Therefore in this section we use the synonymous term "attribute" to refer to these same pieces of data.
