JSON i18n

json_i18n.js

var traverse = require('traverse');

// filter json obj by language
var filter_language = function(language, obj) {
  var result = traverse(obj).map(function(item) {
    if (this.key === language) {
      this.parent.update(item);
    }
  });
  return result;
};

// example object in the multi-lingual format
var obj = {
  "venue_id": "C001",
  "venue_location": {
    "en": "Baker St.",
    "he": "רחוב האופה"
  },
  "venue_name": {
    "en": "Aroma Coffee",
    "he": "קפה ארומה"
  }
};

console.log(filter_language('en', obj));

This is really nice! Did you implemented a fallback language?
