## Description
<section id="description">以前我们使用过代码<code>var myName = &quot;your name&quot;;</code> <code>&quot;your name&quot;</code>被称为<dfn>字符串</dfn> <dfn>文字</dfn> 。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。 </section>
## Instructions
<section id="instructions">创建两个新的<code>string</code>变量: <code>myFirstName</code><code>myLastName</code>并分别为它们分配<code>myFirstName</code><code>myLastName</code>的值。 </section>
## Tests
<section id='tests'>
```yml
tests:
- text: <code>myFirstName</code>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;}})(), "<code>myFirstName</code> should be a string with at least one character in it.");'
- text: <code>myLastName</code>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;}})(), "<code>myLastName</code> should be a string with at least one character in it.");'
