Accesing Nested Object Properties

assign.js

var assignProperty = function (object, property, value) {
  if (typeof property === "string") {
      property = property.split(".");
  }
  if (property.length > 1) {
      var e = property.shift();
      assignProperty(object[e] = Object.prototype.toString.call(object[e]) === "[object Object]" ? object[e] : {}, property, value);
  } else {
      object[property[0]] = value;
  }
};

findProperties.js

var findProperties = function(item, parentProperty){
  var properties = [];
  for (property in item) {
    if (item.hasOwnProperty(property)){
      var propertyName = [parentProperty, property].filter(Boolean).join('.');
      if(typeof item[property] !== 'object') {
        properties.push(propertyName);
      }
      else{
        properties = properties.concat(findProperties(item[property], propertyName));
      }
    }
  }
  return properties;
};

      split(separator).
      reduce(

          }, theObject
      );
  } catch (err) {
