# ARRAY FILTERING

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
var pets = ['cat', 'dog', 'elephant'];

var 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;
}
```

Use `console.log()` to print the `filtered` array to the terminal.

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

`javascripting verify array-filtering.js`
