--- id: 56bbb991ad1ed5201cd392cb title: Manipulate Arrays With push() localeTitle: Manipular matrices con empuje () challengeType: 1 --- ## Description
Una forma fácil de agregar datos al final de una matriz es a través de la función push() . .push() toma uno o más parámetros y los "empuja" al final de la matriz.
var arr = [1,2,3];
arr.push(4);
// arr is now [1,2,3,4]
## Instructions
Presione ["dog", 3] en el extremo de la variable myArray .
## Tests
```yml tests: - text: ' myArray ahora debe ser igual a [["John", 23], ["cat", 2], ["dog", 3]] .' 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), "myArray should now equal [["John", 23], ["cat", 2], ["dog", 3]].");' ```
## Challenge 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. ```
### After Test
```js console.info('after the test'); ```
## Solution
```js var myArray = [["John", 23], ["cat", 2]]; myArray.push(["dog",3]); ```
