Push values from nested objects

Question

I would like to know the best method for grabbing values from nested objects like this one:

var object = {
    1: {
        1: {
        "names": "bob"
        },
        2: {
        "names": "jim"
        }
    }
}

What function or loop would I write to push the values “bob” and “Jim” into an array?

Thank you in advance!

Use nested loops. The outer loop iterates over the properties of `object`, the inner loop iterates over the properties of `object[i]`. — Barmar, Mar 12 '20 at 03:06
Would I nest a loop for every “layer” I am trying to access? — user13048792, Mar 12 '20 at 03:40
Yes. If it has arbitrary hierarchical nesting, you'd use a recursive function. — Barmar, Mar 12 '20 at 03:46
Would you have an example of a recursive function for this scenario where I would want [‘bob’, ‘jim’] as a result? — user13048792, Mar 12 '20 at 04:00
See https://stackoverflow.com/questions/40603913/search-recursively-for-value-in-object-by-property-name for how to search for a property recursively. Instead of returning the value, push it onto the result array. — Barmar, Mar 12 '20 at 04:02
I was able to use nested loops to access the values I wanted; however, it only pushed the last value that met the logic to the array. What am I missing? — user13048792, Mar 12 '20 at 14:13
Is there a reason nested loops would only push the last value — user13048792, Mar 12 '20 at 14:45
Without seeing your code, it's impossible to tell. Common errors I've seen in the past are assigning rather than pushing, or initializing the variable inside the loop instead of before it. — Barmar, Mar 12 '20 at 15:43

you can use Object.values + map

Object.values(object[1]).map(p => p.names)

You're assuming that the top-level object only has one property that's always `object[1]`. That seems unlikely. – Barmar Mar 12 '20 at 03:21
