data JSNode

The JSNode is the building block of the AST. Each has a syntactic part Node. In addition, the leaf elements (terminals) have a position TokenPosn, as well as an array of comments and/or whitespace that was collected while parsing.

Constructors

NN Node

Non Terminal node, does not have any position or comment information

NT Node TokenPosn [CommentAnnotation]

Terminal node, including position and comment/whitespace information
