Get doc value within cloud function

My Cloud Firestore database looks like this:

users
 |          
 |----id----(name,age)
 |----id----(name,age)
 |----id----(name,age)
 |----id----(name,age)
 |----id----(name,age)
...

I'm writing a query through all the elements:

db.collection('users').get()
.then(
    (results) => {          
        results.forEach((doc) => {
            //how to get the id that represents this doc?
        });
        response.json();
    }           
)
.catch(function (error) {
    console.error("Error getting user: ", error);
    response.send(error)
});

My question is simple: the variable doc represents an id (that contains a collection with name and age). How can I get this id? can I retrieve it from doc somehow?

That's actually quite simple. The doc variable is actually DocumentSnapshot, and you get its ID from its id property. So:

db.collection('users').get()
.then(
    (results) => {          
        results.forEach((doc) => {
            console.log(doc.id);
        });
    }           
)
.catch(function (error) {
    console.error("Error getting user: ", error);
    response.send(error)
});
