Lodash sort collection based on external array

arrays, collections, javascript, lodash, underscore.js

Solution

var sortedCollection = _.sortBy(collection, function(item){
  return firstArray.indexOf(item.guid)
});

Problem

I have an array with keys like so: ``` ['asdf12','39342aa','12399','129asg',...] ``` and a collection which has these keys in each object like so: ``` [{guid: '39342aa', name: 'John'},{guid: '129asg', name: 'Mary'}, ... ] ``` Is there a fast way to sort the collection based on the order of keys in the first array?
