Overview

Package ast declares types representing a JavaScript AST.

Warning

The parser and AST interfaces are still works-in-progress (particularly where node types are concerned) and may change in the future.

Functions

func Walk 

func Walk(v Visitor, n Node)

Walk traverses an AST in depth-first order: It starts by calling v.Visit(node); node must not be nil. If the visitor v returned by v.Visit(node) is not nil, Walk is invoked recursively with visitor v for each of the non-nil children of node, followed by a call of v.Visit(nil).
