CONCURRENT ACCESSES OF DYNAMICALLY TYPED OBJECT DATA

A method and an apparatus for an enhanced object model to allow concurrent execution for program code generated from dynamic programming languages, such as JavaScript, are described. An index structure may be introduced to an object model representing a dynamically typed object in addition to a type structure and a data payload storing property or field values of the object. Elements of the index structure may point at corresponding property values as an indirection for accessing the object.
