localeTitle: 将变量附加到字符串
---
## Description
正如我们可以在字符串文字中构建多行的字符串一样，我们也可以使用加号等于（ += ）运算符将变量附加到字符串。
## Instructions
设置someAdjective并使用+=运算符将其附加到myStr 。
## Tests
```yml
tests:
- text: someAdjective应设置为至少3个字符长的字符串
testString: 'assert(typeof someAdjective !== "undefined" && someAdjective.length > 2, "someAdjective should be set to a string at least 3 characters long");'
- text: 使用+=运算符将someAdjective附加到myStr
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
```js
// solution required
