Sort a JSON API response array of objects by a unique key

sorted_objects.js

// Example data from a JSON API that returns an array where each object
// has a unique ID. However the API returns the data in a random order.
var myObjects = [
  {
    data: 'APPL',
    id: 33
  },
  {
    data: 'MSFT',
    id: 241
  },
  {
    data: 'SNAP',
    id: 1543
  }
];
// Array of ids which represent the order we want
var order = [241, 33, 1543];

// Create a meta-object dictionary with mappings between uniqueID -> data
var sortMap = {};
for(o in myObjects) {
  obj = myObjects[o];
  sortMap[parseInt(obj.id)] = obj;
}
console.log(sortMap);

// Create a new array that looks only N times where N is the number of objects
// in your desired order array.
var orderedObjects = [];
for(var i = 0; i < order.length; ++i) {
  orderedObjects.push(sortMap[order[i]]);
}
console.log(orderedObjects);
