Learn JavaScript by adventuring around in the terminal.

There are many ways to manipulate arrays.

One common task is filtering arrays to only contain certain values.

For this we can use the `.filter()` method.

Here is an example:

```js
const pets = ['cat', 'dog', 'elephant']

const filtered = pets.filter(function (pet) {
  return (pet !== 'elephant')
})
```

The `filtered` variable will now only contain `cat` and `dog`.

## The challenge:

Create a file named `array-filtering.js`.

In that file, define a variable named `numbers` that references this array:

```js
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
```

Like above, define a variable named `filtered` that references the result of `numbers.filter()`.

The function that you pass to the `.filter()` method will look something like this:

```js
function evenNumbers (number) {
  return number % 2 === 0
}
```

Pay close attention to the syntax used throughout your solution. Use `console.log()` to print the `filtered` array to the terminal.

Check to see if your program is correct by running this command:

```bash
javascripting verify array-filtering.js
```
