## Hints

### Hint 1

While `push()` added elements to the back of the array, `unshift()` adds them to the front. All you have to do is:

```javascript
var arr = [2, 3, 4, 5];
arr.unshift(1); // Now, the array has 1 in the front

```

Make sure that you are unshifting an array and not each item, example:

`var myArray = ['Hello', 'World']; myArray.unshift(['More stuff', 60]); console.log(myArray); // [['More stuff', 60], 'Hello', 'World']`

i am stuck in this one. it says to append [“Paul”,35] in the beginning.  
below it says myArray should now have [[“Paul”, 35], [“dog”, 3]] so we have to use .shift() as well? to remove [“John”, 23]?

any one?
