| ## Description
 | |
| <section id="description"> Una forma fácil de agregar datos al final de una matriz es a través de la función <code>push()</code> . <code>.push()</code> toma uno o más <dfn>parámetros</dfn> y los "empuja" al final de la matriz. <blockquote> var arr = [1,2,3]; <br> arr.push (4); <br> // arr es ahora [1,2,3,4] </blockquote></section>
 | |
| 
 | |
| ## Instructions
 | |
| <section id="instructions"> Presione <code>["dog", 3]</code> sobre el final de la variable <code>myArray</code> . </section>
 | |
| 
 | |
| ## Tests
 | |
| <section id='tests'>

 | |
|     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>.");'
