How to grab a object property from json with lodash?

I am getting my head around lodash for js and trying to select the object property with the name 'one' from this object by using the id key:

{
   "one": {
      "id":"peter",
      "somevalue":1
         },
   "two": {
      "id":"john",
      "somevalue":1
   }

}

So as a result I would like:

{
   "id":"peter",
   "somevalue":1
}

Sorry I updated the question: How can I accomplish this with lodash returning this result based on the name in this case 'one' by using the key , id='peter'?

With Lodash (#1):

const value = _.find(obj, prop => prop.id === 'peter');

With Lodash (#2):

const value = _.find(obj, {id: 'peter'});

With Lodash (#3): (credit to hughes)

const value = _.find(obj, 'id', 'peter');

Plain JS:

const key = Object.keys(obj).find(key => obj[key].id === 'peter');
const value  obj[key];

Future JS:

const value = Object.values(obj).find(prop => prop.id === 'peter');

More documentation on filter here: https://lodash.com/docs#filter

var obj = {
   "one": {
      "id":"peter",
      "somevalue":1
         },
   "two": {
      "id":"john",
      "somevalue":1
   }

};

console.log(_.filter(obj, {id:"peter"}));
