Answer: Use the jQuery `$.map()` Method

You can simply use the $.map() method to convert a JavaScript object to an array of items.

The $.map() method applies a function to each item in an array or object and maps the results into a new array. Let's take a look at an example to understand how it basically works:

Example

Try this code »

```
<script>
```
```
    var myObj = {
```
```
        name: "Peter",
```
```
        age: 28,
```
```
        gender: "Male",
```
```
        email: "peterparker@mail.com"
```
```
    };
```
```
    
```
```
    // Converting JS object to an array
```

    var array = $.map(myObj, function(value, index){

```
        return [value];
```
```
    });
```
```
    
```
```
    console.log(array);
```

    // Prints: ["Peter", 28, "Male", "peterparker@mail.com"]

```
</script>
```

Let's check out one more example where an object is converted into an array of array:

Example

Try this code »

```
<script>
```
```
    var myObj = {
```
```
        1: ["Peter", "24"],
```
```
        2: ["Harry", "16"],
```
```
        3: ["Alice", "20"]
```
```
    };
```
```
    
```
```
    // Transform JS object to an array
```

    var array = $.map(myObj, function(value, index){

```
        return [value];
```
```
    });
```
```
    
```
```
    console.log(array);
```

    // Output: [["Peter", "24"], ["Harry", "16"], ["Alice", "20"]]

```
</script>
```
