## Description
<section id="description">将数据附加到数组末尾的简单方法是通过<code>push()</code>函数。 <code>.push()</code>接受一个或多个<dfn>参数</dfn>并将它们“推”到数组的末尾。 <blockquote> var arr = [1,2,3]; <br> arr.push（4）; <br> // arr现在是[1,2,3,4] </blockquote></section>

## Instructions
<section id="instructions">将<code>[&quot;dog&quot;, 3]</code>推到<code>myArray</code>变量的末尾。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: '<code>myArray</code>现在应该等于<code>[[&quot;John&quot;, 23], [&quot;cat&quot;, 2], [&quot;dog&quot;, 3]]</code> 。'
    testString: 'assert((function(d){if(d[2] != undefined && d[0][0] == "John" && d[0][1] === 23 && d[2][0] == "dog" && d[2][1] === 3 && d[2].length == 2){return true;}else{return false;}})(myArray), "<code>myArray</code> should now equal <code>[["John", 23], ["cat", 2], ["dog", 3]]</code>.");'

```

## Challenge Seed
<section id='challengeSeed'>

<div id='js-seed'>

```js
// Example
var ourArray = ["Stimpson", "J", "cat"];
ourArray.push(["happy", "joy"]);
// ourArray now equals ["Stimpson", "J", "cat", ["happy", "joy"]]

// Setup
var myArray = [["John", 23], ["cat", 2]];

// Only change code below this line.

```
