Say you want to add an item at the beginning of an array.

To perform this operation you will use the `splice()` method of an array.

`splice()` takes 3 or more arguments. The first is the start index: the place where we'll start making the changes. The second is the delete count parameter. We're **adding** to the array, so the delete count is 0 in all our examples. After this, you can add one or many items to add to the array.

To add at the first position, use `0` as the first argument:

```js
const colors = ['yellow', 'red']

colors.splice(0, 0, 'blue')

//colors === ['blue', 'yellow', 'red']
```
