js-object-iterator

Iterate and update the enumerable properties of an object.

About

This module provides a method to recursively iterate over the enumerable properties of an object. The method takes a callback as an argument that will be called for every non object property. The callback provides handlers to the current object, the current key, and the key's path.

Installation

npm install object-recursive-iterator --save

Module Usage

var iterator = require('object-recursive-iterator');

var myJSONObject = {    // example JSON Object
    'one': {
        'two': {
            'three': {
                'four': '4'
            }
        },
        'six': {
            'seven': '7',
            'eight': '8'
        },
        'nine': '9'
     }
};

iterator.forAll(myJSONObject, function (path, key, obj) {
    console.log('----------');
    console.log('path: ', path);
    console.log('key: ', key);
    console.log('value before processing: ', obj[key]);
    obj[key] += '_processed';   // update value
    console.log('value after processing: ', obj[key]);
    console.log('----------');
});
