Well, I recovered this value from my firebase users node, however I am not able to recover the values, for example: name, cell phone, email.
Note: I have tried this.obj[0]. name; and return me Undefined.

There are several ways depends on what you want? as information if you want to filter by some value if you want to multiply.
the first cases are
const clients = [
{ id: 1, nome: 'Kushter 1' },
{ id: 2, nome: 'Kusther 2' },
{ id: 3, nome: 'Kusther 3' }
];
clients.forEach(item => {
console.log(item.id, item.nome);
});
for (key in clients) {
console.log(clients[key]);
}
See in the documentation of mozila have all the prototypes that can be used in an array just read a few minutes.

Thank you Artsher, but I still get Undefined.

and why you have to loop the key. in your case it will be ['VALORDATA']

Your question is strange, from what you can understand in the question, the question has more to do with
javascriptand how to use objects: see more– tadeubarbosa
Good for your question, from to see that you have no knowledge of the Javascript language, this is not an object is a array object. You will have to go through the array to get the values contained in the object, you can do using Javascript methods as a simple for, foreach or map for example.
