Object to Array in Javascript

Question

I have a object like this one. How can i convert it to Array in JavaScript.

I'm try so hard, but it doesn't work, i can not alert or console.log it.

I have this object below

{
    "2017": {
        "08": [{
            "id": "22",
            "pass": "temp1"
        }, {
            "id": "23",
            "pass": "af",
        }],

        "09": [{
            "id": "25",
            "pass": "zx"

        }]
    },

    "2018": {
        "08": [{
            "id": "24",
            "pass": "gre"
        }]
    }
}

And this is the array i want it to be in JavaScript

Array
(
    [2017] => Array
        (
            [08] => Array
                (
                    [0] => Array
                        (
                            [id] => 22
                            [pass] => temp1
                        )

                    [1] => Array
                        (
                            [id] => 23
                            [pass] => af
                        )

                )

            [09] => Array
                (
                    [0] => Array
                        (
                            [id] => 25
                            [pass] => zx

                        )

                )

        )

    [2018] => Array
        (
            [08] => Array
                (
                    [0] => Array
                        (
                            [id] => 24
                            [pass] => gre
                        )

                )

        )

)

Thank you very much for answering

You can use [`Object.keys()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys) or [`Object.values()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_objects/Object/values) — Hassan Imam, Sep 07 '17 at 05:59
can you make an example for me, i'm just start to program on javascript — Hoàng Nguyễn, Sep 07 '17 at 06:00
Update the question with your desired array, then it would be easier for other user to solve the problem — Hassan Imam, Sep 07 '17 at 06:01
Show us how would you like the array to look like. Like: I have THIS, and I want it to be THAT — Sebastian Kaczmarek, Sep 07 '17 at 06:06
That's the correct representation of the array in Javascript. PHP doesn't distinguish between associative and indexed arrays, JS does - assoc arrays are objects. What *exactly* do you want to do with the object? if you simply want to loop through it, you can use the `for..in` loop, see Sebastian's answer. — marekpw, Sep 07 '17 at 06:13
I want to alert loop to alert id and pass althought i don't know the key 2017 2018 and 08 09 — Hoàng Nguyễn, Sep 07 '17 at 06:15
The array you posted is PHP associative array. Which in JavaScript is represented as Object which you already have. See my answer to know how to iterate over it — Sebastian Kaczmarek, Sep 07 '17 at 06:15

For the very first, I would like to tell you that this isn't a mere JavaScript object, it's a list of JSON objects.

Get this list in some variable and then use it like given in below link.

But it is a JS object. – marekpw Sep 07 '17 at 06:07
You're right. This is a object, but concern is, what the object contains. It contains a list of objects. – Ammar Shahid Sep 07 '17 at 06:10
As per the code snippet in question, the JS object contains a JSON list of objects. – Ammar Shahid Sep 07 '17 at 06:12

You can use underscore.js to do this:

_(obj).each(function(elem, key){
   arr.push(elem[0]);
});

Why underscore.js? There is easy pure JS solution for this. There is no need to load any library for that – Sebastian Kaczmarek Sep 07 '17 at 06:18

If all you want to achieve is to loop through the object you don't have to convert it to an array. In JavaScript, there is for...in loop which will be perfect in this case. Use it like this:

var myobj = {
    key1: "val1",
    key2: "val2",
    key3: "val3",
}

for(var key in myobj){
    var value = myobj[key];

    console.log(key, value);
}
