Convert recursive array object to flat array object

Question

I'm looking for a way to convert this array of recursive objects into a flat array of objects to make it easier to work with.

[
  {
    "name": "bill",
    "car": "jaguar",
    "age": 30,
    "profiles": [
      {
        "name": "stacey",
        "car": "lambo",
        "age": 23,
        "profiles": [
          {
            "name": "martin",
            "car": "lexus",
            "age": 34,
            "profiles": []
          }
        ]
      }
    ]
  }
]

This is the expected output.

[
  {
    "name": "bill",
    "car": "jaguar",
    "age": 30,
  },{
    "name": "stacey",
    "car": "lambo",
    "age": 23,
  },{
    "name": "martin",
    "car": "lexus",
    "age": 34,
  }
]

Each profiles array can have n amount of items, which may or may not have an empty array of sub profiles. Note the converted array objects don't contain profiles after the conversion.

I'm open to using underscore or lodash to achieve this.

Let's call your original data o, combining Array.prototype.reduce with recursion I came up with this:

o.reduce(function recur(accumulator, curr) {
   var keys = Object.keys(curr);
   keys.splice(keys.indexOf('profiles'), 1);

   accumulator.push(keys.reduce(function (entry, key) {
       entry[key] = curr[key];
       return entry;
   }, {}));

   if (curr.profiles.length) {
       return accumulator.concat(curr.profiles.reduce(recur, []));
   }

   return accumulator;
}, []);
