Remove base key object from array of object using lodash or javascript

Question

I have the array of objects as below which has a base object with a set of values.

I need to remove the base object of all the data and make it as the Expected result below.

Example array

[
     {
        "100": {
            "id": "100",
            "name": "Test name 1"
        },
        "101": {
            "id": "101",
            "name": "Test name 2"
        },
        "102": {
            "id": "102",
            "name": "Test name 3"
        }

     }
]

Expected Result

[        
        {
            "id": "100",
            "name": "Test name 1"
        },
        {
            "id": "101",
            "name": "Test name 2"
        },
        {
            "id": "102",
            "name": "Test name 3"
        }         
]

You can iterate with Array.map(), get the values of the object with Object.values(), and flatten the results to a single array by spreading into Array.concat():

const data = [{"100":{"id":"100","name":"Test name 1"},"101":{"id":"101","name":"Test name 2"},"102":{"id":"102","name":"Test name 3"}}];

const result = [].concat(...
  data.map(o => Object.values(o))
);

console.log(result);

With lodash you can use _.flatMap() with _.values():

const data = [{"100":{"id":"100","name":"Test name 1"},"101":{"id":"101","name":"Test name 2"},"102":{"id":"102","name":"Test name 3"}}];

const result = _.flatMap(data, _.values);

console.log(result);
