Walks a JavaScript AST, such as one supplied via
esprima, and adds a parent
property to each node.
Makes it much easier to navigate the AST, and the parent properties
added here are non-enumerable so you can still serialize the tree to JSON
without JSON.stringify throwing an error.
Usage
require('ast-parents')(ast)
Where ast is an AST object. For example:
var esprima = require('esprima')
var fs = require('fs')
var src = fs.readFileSync(__filename, 'utf8')
var ast = esprima.parse(src)
parents(ast)
ast.body[0].parent === ast.body
