pickDeep function (like lodash pick function but with recursivity). Demo : https://jsbin.com/demaveq/edit?js,console

pickDeep-example.js

var test = {
  key1: {
    key11: 'test11',
    key13: 'test13'
  },
  key2: 'test2'
};

var source = {
  key1: {
    key11: 'source11',
    key12: 'source12'
  },
  key2: 'hello'
};

function pickDeep(collection, source) {
  _.mapValues(collection, (value, key, object) => {
      if (_.isObject(value)) {
        // todo recursive
        pickDeep(value, source[key])
      } else {
        if (typeof source[key] === "undefined") {
           delete object[key];
        } else {
          return value;
        }
      }
    });
  return collection;
}

console.log(pickDeep(test, source));
