---
## Description
Del mismo modo que podemos construir una cadena sobre varias líneas a partir de literales de cadena, también podemos agregar variables a una cadena utilizando el operador más es igual a ( += ).
## Instructions
Configure someAdjective y someAdjective a myStr usando el operador += .
## Tests
```yml
tests:
- text: someAdjective debe establecerse en una cadena de al menos 3 caracteres de largo
testString: 'assert(typeof someAdjective !== "undefined" && someAdjective.length > 2, "someAdjective should be set to a string at least 3 characters long");'
- text: someAdjective de someAdjective a myStr usando el operador +=
testString: 'assert(code.match(/myStr\s*\+=\s*someAdjective\s*/).length > 0, "Append someAdjective to myStr using the += operator");'
```
## Challenge Seed
```js
// Example
var anAdjective = "awesome!";
var ourStr = "freeCodeCamp is ";
ourStr += anAdjective;
// Only change code below this line
var someAdjective;
var myStr = "Learning to code is ";
```
### After Test
```js
console.info('after the test');
```
## Solution
