## Description
<section id='description'>
With JavaScript <code>array</code> variables, we can store several pieces of data in one place.
You start an array declaration with an opening square bracket, end it with a closing square bracket, and put a comma between each entry, like this:
<code>var sandwich = ["peanut butter", "jelly", "bread"]</code>.
</section>

## Instructions
<section id='instructions'>
Modify the new array <code>myArray</code> so that it contains both a <code>string</code> and a <code>number</code> (in that order).
<strong>Hint</strong><br>Refer to the example code in the text editor if you get stuck.
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>myArray</code> should be an <code>array</code>.
    testString: assert(typeof myArray == 'object', '<code>myArray</code> should be an <code>array</code>.');
  - text: The first item in <code>myArray</code> should be a <code>string</code>.
    testString: assert(typeof myArray[0] !== 'undefined' && typeof myArray[0] == 'string', 'The first item in <code>myArray</code> should be a <code>string</code>.');
  - text: The second item in <code>myArray</code> should be a <code>number</code>.
    testString: assert(typeof myArray[1] !== 'undefined' && typeof myArray[1] == 'number', 'The second item in <code>myArray</code> should be a <code>number</code>.');

```
