Get name of the first child in a object

Question

I have following Object:

bots: {
    bot_1: {
      [...]
    },
    bot_2: {
      [...]
    },
    bot_3: {
      [...]
    }
    ...
},

How could I get the name of the first child? In this case 'bot_1'. Thanks!

EDIT: I should have searched a bit more since it is a pretty basic question. I tried searching for the answer but I couldn't find it because I didn't know that it is called "property". Anyways, thanks for your help

`bot_1` is not the first child. Objects are unordered. The first key for one browser could differ to the next browser. — tymeJV, Oct 11 '17 at 18:28
`name`? do you mean `key`?...`value`?...`blood type`? `Favorite color`? — zer00ne, Oct 11 '17 at 18:28

You can do this

bots[Object.keys(bots)[0]];

to get the first key of your object. However, you may not get bot_1 always since the keys are unordered

Important to note that object properties are not ordered so if you want it to always return "bot_1" you have to search the .keys() array. – terpinmd Oct 11 '17 at 18:31
