If I understand what you're saying, there are two ways:

1. Define the array as a global array object:

   JS_DefineProperty(cx, global, "myarray", OBJECT_TO_JSVAL(myarray), 
nil, nil, 0);

   (To define the array as a property of any other object, simply 
replace global with another JSObject instance.)

2. You could pass the array as a parameter to a js function:

   JS_CallFunctionName(cx, global, "myfunc", 1, 
OBJECT_TO_JSVAL(myarray), @rval);

Does that answer your question?
