 **目标：** 构建一个功能类似于此的[CodePen.io](https://codepen.io)应用程序： [https](https://codepen.io/freeCodeCamp/full/Myvqmo/) **：** [//codepen.io/freeCodeCamp/full/Myvqmo/](https://codepen.io) 。完成以下[用户故事](https://en.wikipedia.org/wiki/User_story) 。使用您需要的任何库或API。给它你自己的个人风格。 **用户故事：** 我可以看到freeCodeCamp当前是否在Twitch.tv上流式传输。 **用户故事：** 我可以点击状态输出并直接发送到freeCodeCamp的Twitch.tv频道。 **用户故事：** 如果Twitch用户当前正在播放，我可以看到有关他们正在播放的内容的其他详细信息。 **提示：** 请参阅[http://forum.freecodecamp.org/t/use-the-twitchtv-json-api/19541上](http://forum.freecodecamp.org/t/use-the-twitchtv-json-api/19541)对Twitch.tv的JSONP API的示例调用。 **提示：** 有关此API调用的相关文档位于： [https](https://dev.twitch.tv/docs/v5/reference/streams/#get-stream-by-user) ： [//dev.twitch.tv/docs/v5/reference/streams/#get-stream-by-user](https://dev.twitch.tv/docs/v5/reference/streams/#get-stream-by-user) 。 **提示：** 这是定期传输的人的Twitch.tv用户名数组： `["ESL_SC2", "OgamingSC2", "cretetion", "freecodecamp", "storbeck", "habathcx", "RobotCaleb", "noobs2ninjas"]` **更新：** 由于[此处](https://blog.twitch.tv/client-id-required-for-kraken-api-calls-afbb8e95f843#.f8hipkht1)解释的API使用条件发生变化，Twitch.tv现在需要API密钥，但我们已经构建了一种解决方法。使用[https://wind-bow.glitch.me/twitch-api](https://wind-bow.glitch.me)而不是twitch的API基本URL（即`https://api.twitch.tv/kraken），您仍然可以获取帐户信息，而无需注册API密钥。如果卡住，请记得使用`[Read-Search-Ask](https://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck-coding/19514) 。完成后，单击“我已完成此挑战”按钮并包含指向CodePen的链接。您可以通过Facebook上的朋友分享您的项目反馈。

-# How the formatter works
-
-## Validation
-
-There are two scripts that validate challenges: validate-text and
-validate-hints. validate-text ensures that any code inside <code> tags can
-be converted to backticks.  For example <code>var x = 'y';</code> is fine, but
-<code><span>not okay</span><code> is not, since `<span>not okay</span>` becomes
-<code>&lt;span&gt;not okay&lt;/span&gt;<code> which is not the intention.
-
-In contrast <code>&lt;span&gt;span we want&lt;/span&gt;<code> is perfectly fine.
-The script will parse this and replace it with `<span>span we want</span>`.
-
-Some challenges will break, so it's worth checking how they're rendered after
-transform-challenges has done its work.
-
-validate-hints operates differently. It checks to see if there is any markdown
-syntax inside the test text and flags up challenges that *may* not be being
-rendered correctly. Unfortunately there are a lot of false positives, a human
-needs to see if the challenge author intended for the text to be parsed as
-markdown or not.  Also bare email addresses name@address.com should be
-highlighted by this tool and will need wrapping with backticks.
-
-## How to use
-
-mmv is great, so I recommend installing that first.  Then:
-
-cd curriculum/challenges/chinese/12-certificates
-mmv ";*.md" "#1#2.markdown"
-cd ../../../../tools/scripts/formatter/fcc-md-to-gfm/
-node formatCurriculum.js
-cd ../md-to-mdx
-node md-to-mdx # this might have warnings and errors.  Errors need fixing, but warnings just need checking
-cd ../../../../curriculum/challenges/chinese/
-mmv -md ";*.mdx" "#1#2.md"

-## Description
-<section id='description'>
-Two integers $N$ and $M$ are said to be <a href='https://en.wikipedia.org/wiki/Amicable numbers' title='wp: Amicable numbers' target='_blank'>amicable pairs</a> if $N \neq M$ and the sum of the <a href="https://rosettacode.org/wiki/Proper divisors" title="Proper divisors" target="_blank">proper divisors</a> of $N$ ($\mathrm{sum}(\mathrm{propDivs}(N))$) $= M$ as well as $\mathrm{sum}(\mathrm{propDivs}(M)) = N$.
-<strong>Example:</strong>
-<strong>1184</strong> and <strong>1210</strong> are an amicable pair, with proper divisors:
-<ul>
-  <li>1, 2, 4, 8, 16, 32, 37, 74, 148, 296, 592  and</li>
-  <li>1, 2, 5, 10, 11, 22, 55, 110, 121, 242, 605   respectively.</li>
-</ul>
-</section>

-## Description
-
-<section id='description'>
-
-Two integers $N$ and $M$ are said to be [amicable pairs](<https://en.wikipedia.org/wiki/Amicable numbers> "wp: Amicable numbers") if $N \\neq M$ and the sum of the [proper divisors](<https://rosettacode.org/wiki/Proper divisors> "Proper divisors") of $N$ ($\\mathrm{sum}(\\mathrm{propDivs}(N))$) $= M$ as well as $\\mathrm{sum}(\\mathrm{propDivs}(M)) = N$.
-
-**Example:**
-
-**1184** and **1210** are an amicable pair, with proper divisors:
-
-<ul>
-  <li>1, 2, 4, 8, 16, 32, 37, 74, 148, 296, 592  and</li>
-  <li>1, 2, 5, 10, 11, 22, 55, 110, 121, 242, 605   respectively.</li>
-</ul>

-This button would take up 100% of the available width.

-## Description
-<section id='description'>
-With CSS, there are hundreds of CSS properties that you can use to change the way an element looks on your page.
-When you entered <code>&#60;h2 style="color: red;"&#62;CatPhotoApp&#60;/h2&#62;</code>, you were styling that individual <code>h2</code> element with inline CSS, which stands for Cascading Style Sheets.
-That's one way to specify the style of an element, but there's a better way to apply CSS.
-At the top of your code, create a <code>style</code> block like this:
-
-```html
-<style>
-</style>
-```
-
-Inside that style block, you can create a <dfn>CSS selector</dfn> for all <code>h2</code> elements. For example, if you wanted all <code>h2</code> elements to be red, you would add a style rule that looks like this:
-
-```html
-<style>
-  h2 {
-    color: red;
-  }
-</style>
-```
-
-Note that it's important to have both opening and closing curly braces (<code>{</code> and <code>}</code>) around each element's style rule(s). You also need to make sure that your element's style definition is between the opening and closing style tags. Finally, be sure to add a semicolon to the end of each of your element's style rules.
-</section>
-
-## Instructions
-<section id='instructions'>
-Delete your <code>h2</code> element's style attribute, and instead create a CSS <code>style</code> block. Add the necessary CSS to turn all <code>h2</code> elements blue.
-</section>
-
-## Tests
-<section id='tests'>
-
-```yml
-tests:
-  - text: The style attribute should be removed from your <code>h2</code> element.
-    testString: assert(!$("h2").attr("style"));
-  - text: You should create a <code>style</code> element.
-    testString: assert($("style") && $("style").length >= 1);
-  - text: Your <code>h2</code> element should be blue.
-    testString: assert($("h2").css("color") === "rgb(0, 0, 255)");
-  - text: Your stylesheet <code>h2</code> declaration should be valid with a semicolon and closing brace.
-    testString: assert(code.match(/h2\s*\{\s*color\s*:.*;\s*\}/g));
-  - text: All your <code>style</code> elements should be valid and have closing tags.
-    testString: assert(code.match(/<\/style>/g) && code.match(/<\/style>/g).length === (code.match(/<style((\s)*((type|media|scoped|title|disabled)="[^"]*")?(\s)*)*>/g) || []).length);

-## Description
-
-<section id='description'>
-
-Given a list of values and a set of integer indices into that value list, the task is to sort the values at the given indices, but preserving the values at indices outside the set of those to be sorted.
-
-Make your function work with the following list of values and set of indices:
-
-<code>values: [7, <b>6</b>, 5, 4, 3, 2, <b>1</b>, <b>0</b>]</code>
-
-`indices(0-based): {6, 1, 7}`
-
-Where the correct result would be:
-
-<code>[7, <b>0</b>, 5, 4, 3, 2, <b>1</b>, <b>6</b>]</code>.

-<strong>User Story #1:</strong> I should be able to see an outer container with a corresponding <code>id="drum-machine"</code> that contains all other elements.
-<strong>User Story #2:</strong> Within <code>#drum-machine</code> I can see an element with a corresponding <code>id="display"</code>.

The drum pads MUST be in this order.
-<strong>User Story #4:</strong> Within each <code>.drum-pad</code>, there should be an HTML5 <code>audio</code> element which has a <code>src</code> attribute pointing to an audio clip, a class name of <code>clip</code>, and an id corresponding to the inner text of its parent <code>.drum-pad</code> (e.g. <code>id="Q"</code>, <code>id="W"</code>, <code>id="E"</code> etc.).

-## Description
-<section id='description'>
-Welcome to freeCodeCamp's HTML coding challenges. These will walk you through web development step-by-step.
-First, you'll start by building a simple web page using HTML. You can edit code in your code editor, which is embedded into this web page.
-Do you see the code in your code editor that says <code>&#60;h1&#62;Hello&#60;/h1&#62;</code>? That's an HTML element.
-Most HTML elements have an opening tag and a closing tag.
-Opening tags look like this:
-<code>&#60;h1&#62;</code>
-Closing tags look like this:
-<code>&#60;/h1&#62;</code>
-The only difference between opening and closing tags is the forward slash after the opening bracket of a closing tag.
-Each challenge has tests you can run at any time by clicking the "Run tests" button. When you pass all tests, you'll be prompted to submit your solution and go to the next coding challenge.
-<strong>Note:</strong>&nbsp;Testing non-breaking note stuff.
-</section>
-
-## Instructions
-<section id='instructions'>
-To pass the test on this challenge, change your <code>h1</code> element's text to say "Hello World".

-forumTopicId: 301098
----
-
-## Description
-<section id='description'>
-<code>a</code> (<i>anchor</i>) elements can also be used to create internal links to jump to different sections within a webpage.
-To create an internal link, you assign a link's <code>href</code> attribute to a hash symbol <code>#</code> plus the value of the <code>id</code> attribute for the element that you want to internally link to, usually further down the page. You then need to add the same <code>id</code> attribute to the element you are linking to. An <code>id</code> is an attribute that uniquely describes an element.
-Below is an example of an internal anchor link and its target element:
-
-```html
-<a href="#contacts-header">Contacts</a>
-...
-<h2 id="contacts-header">Contacts</h2>
-```
-
-When users click the Contacts link, they'll be taken to the section of the webpage with the <b>Contacts</b> header element.
-</section>
-
-## Instructions
-<section id='instructions'>
-Change your external link to an internal link by changing the <code>href</code> attribute to "#footer" and the text from "cat photos" to "Jump to Bottom".
-Remove the <code>target="_blank"</code> attribute from the anchor tag since this causes the linked document to open in a new window tab.
-Then add an <code>id</code> attribute with a value of "footer" to the <code>&lt;footer&gt;</code> element at the bottom of the page.

-You can nest links within other text elements.
-
-```html
-<p>
-  Here's a <a target="_blank" href="http://freecodecamp.org"> link to freecodecamp.org</a> for you to follow.
-</p>
-```
-
-Let's break down the example:
-Normal text is wrapped in the <code>p</code> element:<br> <code>&#60;p&#62; Here's a ... for you to follow. &#60;/p&#62;</code>
-Next is the <i>anchor</i> element <code>&#60;a&#62;</code> (which requires a closing tag <code>&#60;/a&#62;</code>):<br>  <code>&#60;a&#62; ... &#60;/a&#62;</code>
-<code>target</code> is an anchor tag attribute that specifies where to open the link and the value <code>"_blank"</code> specifies to open the link in a new tab
-<code>href</code> is an anchor tag attribute that contains the URL address of the link:<br>  `<a href="http://freecodecamp.org"> ... </a>`
-The text, <strong>"link to freecodecamp.org"</strong>, within the <code>a</code> element called <code>anchor text</code>, will display a link to click:<br>  <code>&#60;a href=" ... "&#62;link to freecodecamp.org&#60;/a&#62;</code>
-The final output of the example will look like this:<br><p>Here's a <a target="_blank" href="http://freecodecamp.org"> link to freecodecamp.org</a> for you to follow.</p>
-</section>

-Now nest the existing <code>a</code> element within a new <code>p</code> element (just after the existing <code>main</code> element). The new paragraph should have text that says "View more cat photos", where "cat photos" is a link, and the rest of the text is plain text.

-<section id='description'>
-
-Produce a spiral array. A *spiral array* is a square arrangement of the first N<sup>2</sup> natural numbers, where the numbers increase sequentially as you go around the edges of the array spiraling inwards. For example, given **5**, produce this array:
-
-<pre>
-0  1  2  3  4
-15 16 17 18 5
-14 23 24 19 6

-## Description
-<section id='description'>
-We will now use our knowledge of strings to build a "<a href='https://en.wikipedia.org/wiki/Mad_Libs' target='_blank'>Mad Libs</a>" style word game we're calling "Word Blanks". You will create an (optionally humorous) "Fill in the Blanks" style sentence.
-In a "Mad Libs" game, you are provided sentences with some missing words, like nouns, verbs, adjectives and adverbs. You then fill in the missing pieces with words of your choice in a way that the completed sentence makes sense.
-Consider this sentence - "It was really <strong>____</strong>, and we <strong>____</strong> ourselves <strong>____</strong>". This sentence has three missing pieces- an adjective, a verb and an adverb, and we can add words of our choice to complete it. We can then assign the completed sentence to a variable as follows:
-
-```js
-var sentence = "It was really " + "hot" + ", and we " + "laughed" + " ourselves " + "silly" + ".";
-```
-
-</section>
-
-## Instructions
-<section id='instructions'>
-In this challenge, we provide you with a noun, a verb, an adjective and an adverb. You need to form a complete sentence using words of your choice, along with the words we provide.
-You will need to use the string concatenation operator <code>+</code> to build a new string, using the provided variables: <code>myNoun</code>, <code>myAdjective</code>, <code>myVerb</code>, and <code>myAdverb</code>. You will then assign the formed string to the <code>wordBlanks</code> variable.  You should not change the words assigned to the variables.
-You will also need to account for spaces in your string, so that the final sentence has spaces between all the words. The result should be a complete sentence.

-/* Currently the challenge parser behaves differently depending on whether a
-section starts with an empty line or not.  If it does not, the parser interprets
-single new-line (\n) characters as paragraph breaks.  It also does not parse
-markdown syntax (such as `).  This makes formatting challenges harder than it
-needs to be, since normal markdown rules do not apply (some of the time!)
-
-For example
-<section id='instructions'>
-Sentence1.
-Sentence2 `var x = 'y'`.
-...
-
-becomes
-
-
-Sentence1.
-
-Sentence2 `var x = 'y'`.
-
-
-in the challenge, but should become
-
-
-Sentence1. Sentence2 <code>var x = 'y'</code>.
-
----
-
-This file converts the instructions and descriptions.  After this there will be
-no need to handle the case where the first line is not empty and markdown syntax
-will always work.  The linter can check that the first blank line exists.
