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:

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

var filtered = pets.filter(function (pet) {
  return (pet !== 'elephant');
});

The filtered variable will now only contain cat and dog.

Create a file named array-filtering.js.

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

[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:

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:
