Get the value of an Element in an array

i'm trying to get the value of a Object in my array. Basically when i'm doing

var firsts = response.data;
console.log(firsts)

I have something like that

{
 "EUR_BND": 1.603476
}

But the name of the object is changing every time, so i can't do

response.data.EUR_BND

I wondered if there was a way to directly get the value of the only object, without having to go through its name.

The best way for me, is to get the list of keys and then you can do whatever you want with it,
Maybe your need can evolve in the future, so it is recommended that you start by getting your keys and do the logic you wish

var keys = Object.keys(data);
if(keys && keys.length>0)
{
var firstValue = data[keys[0]];
//other staff
}

This is how you may access "EUR_BND" key within response.data or firsts object.

var firsts = response.data;
var keys = Object.keys(firsts);
console.log(firsts[keys[0]]);

I would suggest having a look at Object.keys method here

Object.values gives you a list of all values of a object keys, you can use it

<script>
data = {
 "EUR_BND": 1.603476
};
value_a = Object.values(data)[0];
console.log(value_a); #1.603476
</script>

This way you don't need to use the object key to get the value

Try best way to get all key and value in loop

const data = {
 "EUR_BND": 1.603476,
 "TEST_BND": 3.4,
 "TEST2_BND": 5.6
}
    var key;

for (key in data) {
    console.log(key+' '+data[key])
}

You could retrieve the keys with

Object.keys(obj)

like it is stated in the docs and then access the value like you normally would:

Using Object.values:

const data = {
 "EUR_BND": 1.603476,
 "TEST_BND": 3.4,
 "TEST2_BND": 5.6
}

console.log(Object.values(data))

You can use the object.values

Object.values(response.data)

Which would return an array of the values in the object

Object.values(response.data)[0] would return the value if you have one
