JSON/JS- Getting JSON object name

I have the following object consisting of three other objects of type array :

enter image description here

I want to get the text samsung out of that object and the rest of the objects. I have tried using a for in loop but I am getting the keys 0, 1 , 2. 

for(brand in brands){
 console.log(brand)  // prints out `0, 1 , 2`
}

so I added another nested for in loop, but than I get 0, 0, 0 which are the keys within samsung, and other array objects within the rest of the objects.

What am i missing ?

You can try 

for(brand in brands[0]){
  console.log(brand);
}

assuming the name of the array to be brands

EDIT

For all the elements in the array brands

brands.forEach(function(v){
    for(brand in v){
      console.log(brand);
    }
});

Your loop is looping through the entire array, rather than the keys of an object.

var brand = brands[0];
for ( var i in brand )
  console.log( brand[i] ) // -> samsung

Or to get them all:

for ( var i = 0; i < brands.length; i++){
    var brand = brands[i];
    for ( var i in brand )
      console.log( brand[i] ) // -> samsung
}

You can use Object.keys(brands[brand]), and, based on your example, you would want Object.keys(brands[brand])[0]
