## Description
|

<section id='description'>
|
||
请注意，本项目在 <a href="https://repl.it/github/freeCodeCamp/boilerplate-mochachai">这个 Repl.it 项目</a> 的基础上进行开发。你也可以从 <a href='https://repl.it/github/freeCodeCamp/boilerplate-mochachai'>GitHub</a> 上克隆。

||
<code>isOk()</code> 用来测试值是否为 <code>truthy</code>；<code>isNotOk()</code> 用来测试值是否为 <code>falsy</code>。
|
||
如果你想了解更多关于 truthy 和 falsy 值的内容，请参阅 <a href="https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-algorithm-scripting/falsy-bouncer" target="_blank">Falsy Bouncer</a> 这道挑战题目。

|
||
- text: 请选择正确的断言—isOk 或 isNotOk
|
||
