How to use _lodash to retrieve value from Objects in Array?

Question

Here is my Array containing Objects, each Object has a ticker value:

[Object]
0: Object
    $$hashKey: "object:130"
    tags: Array[1]
    ticker: Object
        company: "Alcoa Inc."
        direction: "negative"
        percent: -3.89
        price: 14.59
        selected: true
        ticker: "AA"

There could be several objects, how would one use the _lodash library to pull out the ticker.ticker values out of each Object?

enter image description here

I've looked at their each and find methods, but they are used on very basic arrays, with no documentation on how to target key value pairs inside.

_.each([1, 2, 3], alert);

_.reduce(list, iteratee, [memo], [context])

Ideally, what I'm trying to do is take that Array, and produce something like:

ticker1 = ticker1, & ticker2 = ticker2 or

[ticker1, ticker2]

You can use _.pluck: https://lodash.com/docs#pluck

console.log(_.pluck(_.pluck(list, 'ticker'), 'ticker'));

You can provide a property path to pluck():

_.pluck(list, 'ticker.ticker');
