object-walk

Walks through an object executing user defined functions at every node on the
way down and back up. Functions will be given three arguments: the value
of the current node, the name of the current node, and the object being
being walked through. This roughly resembles the callback signature of
Array.prototype.map.

Installation

``
npm install object-walk
`

Usage

In node:

`
objectWalk = require('object-walk');
var obj = {
child1 : {
data : "some data"
},
child2 : {
data : "some data"
}
};
function descentionFn (val, prop, obj) {
if (val === "some data") {
obj[prop] = "changed";
}
}
objectWalk(obj, descentionFn);
`

`
var obj = {
child1 : {
data : {
child3 : {
data : "some data"
},
child4 : {
data : "some data"
}
}
},
child2 : {
data : "some data"
}
};
function ascentionFn (val, prop, obj) {
if (prop === "data") {
delete obj[prop].child3;
}
if (prop === "child4") {
obj[prop].data = "changed";
}
}
objectWalk(obj, null, ascentionFn);
