How to extract the property values of a JavaScript object

Question

How can I extract the following value of the variable Test? "test_bookmarks", "Janice Scott", "Birmingham all" from the javascript object into another variable?

The image comes from the console log of Google Chrome.

Right click on the property you want and chose `copy property path` — Rainbow, May 15 '18 at 12:27
@Bombo: Check my answer. It will run because I am enclosing property name in a string. — Rehmat, May 15 '18 at 12:41

let states = e.$$state.value;
let labels = states.map(state => state.label); //[ 'test_bookmarks', 'Janice Scott', 'Birmingham_bil' ]

for (var i=0; i<=e["$$state"].value.length-1; i++) {
    var obj = e["$$state"].value[i];
    console.log(obj.label);
}

sorry I didn't specify that the object js is inside a variable for example "test" – Bombo May 15 '18 at 12:45
@Bombo: Do you mean `test.e["$$state"].value`? – Rehmat May 15 '18 at 12:47
The variabile "test " contains the image object – Bombo May 15 '18 at 12:53

If you see the value of "value" key, it tells you that it is an array. That means the if you do something like:

$$state.value[*].label

here * stands for any integer, this way you'll get the values of the label property.

So, if you want to access the first label then it would be like:

$$state.value[0].label

this will give you "test_bookmarks".
