Stack scopes / bindings?

[A. Sundararajan]

Hi.

A script engine has an associated (default) ScriptContext instance. A 
ScriptContext has  ENGINE_SCOPE and GLOBAL_SCOPE bindings in it.

ENGINE_SCOPE which is the same as a "global" object of ECMAScript (has 
properties like "Object", "Function", "undefined", "parseInt" etc.). If 
a variable is missing in ENGINE_SCOPE, then it is searched in GLOBAL_SCOPE.

For more details, please check out

Hope this helps,
-Sundar
