AST node for an Array literal.
AST node for an Array literal. The elements list will always be non- null , although the list will have no elements if the Array literal is empty.

Node type is Rhino.Token.ARRAYLIT .

ArrayLiteral : [ Elisionopt ] [ ElementList ] [ ElementList , Elisionopt ] ElementList : Elisionopt AssignmentExpression ElementList , Elisionopt AssignmentExpression Elision : , Elision ,
