walk the ast with references to parent nodes
npm install astwwalk the ast


This module is a faster version of
falafel
that only does ast walking and .parent tracking, not source transforms.
`` js
var astw = require('astw');
var deparse = require('escodegen').generate;
var walk = astw('4 + beep(5 * 2)');
walk(function (node) {
var src = deparse(node);
console.log(node.type + ' :: ' + JSON.stringify(src));
});
`
` js`
var astw = require('astw')
Return a walk() function from the source string or ast object src.
Optionally:
* opts.ecmaVersion - default: 8
Walk the nodes in the ast with cb(node) where node is each element in the.parent
ast from esprima but with an additional
reference to the parent node.
With npm do:
```
npm install astw
