Given a JavaScript object: 

var dataObject = {
   object1: {id: 1, name: "Fred"}, 
   object2: {id: 2, name: "Wilma"}, 
   object3: {id: 3, name: "Pebbles"}
};

How do I efficiently extract the inner objects into an array? I do not need to maintain a handle on the object[n] IDs.

var dataArray = [
    {id: 1, name: "Fred"}, 
    {id: 2, name: "Wilma"}, 
    {id: 3, name: "Pebbles"}]

I prefer to destruct object values into array:

[...Object.values(dataObject)]

var dataObject = {
   object1: {id: 1, name: "Fred"}, 
   object2: {id: 2, name: "Wilma"}, 
   object3: {id: 3, name: "Pebbles"}
};

var dataArray = [...Object.values(dataObject)];

This one worked for me

var dataArray = Object.keys(dataObject).map(function(k){return dataObject[k]});
