## Description
以前我们使用过代码var myName = "your name"; "your name"被称为字符串 文字 。它是一个字符串，因为它是用单引号或双引号括起来的一系列零个或多个字符。
## Instructions
创建两个新的string变量： myFirstName和myLastName并分别为它们分配myFirstName和myLastName的值。
## Tests
```yml
tests:
- text: myFirstName应该是一个至少包含一个字符的字符串。
testString: 'assert((function(){if(typeof myFirstName !== "undefined" && typeof myFirstName === "string" && myFirstName.length > 0){return true;}else{return false;}})(), "myFirstName should be a string with at least one character in it.");'
- text: myLastName应该是一个至少包含一个字符的字符串。
testString: 'assert((function(){if(typeof myLastName !== "undefined" && typeof myLastName === "string" && myLastName.length > 0){return true;}else{return false;}})(), "myLastName should be a string with at least one character in it.");'
```
