* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

5a24bbe0dba28a8d3cbd4c5d 創建一個複雜的 JSX 元素 6 301382 create-a-complex-jsx-element

--description--

上一個挑戰是 JSX 的一個簡單示例,但 JSX 也可以表示更復雜的 HTML。

關於嵌套的 JSX需要知道的一件重要的事情那就是它必須返回單個元素。

這個父元素將包裹所有其他級別的嵌套元素。

例如,幾個作爲兄弟元素編寫的 JSX 元素而沒有父元素包裹將不會被轉換。

這裏是一個示例:

有效的 JSX

<div>
  <p>Paragraph One</p>
  <p>Paragraph Two</p>
  <p>Paragraph Three</p>
</div>

無效的 JSX

<p>Paragraph One</p>
<p>Paragraph Two</p>
<p>Paragraph Three</p>

--instructions--

定義一個新的常量 JSX,渲染一個 div,其中依次包含以下元素:

一個 h1,一個 p,一個包含三個 li 項的無序列表。 可以在每個元素中包含任意文本。

注意: 當像這樣渲染多個元素時,可以把它們都用圓括號括起來,但是這並不是必須的。 另外,此挑戰使用 div 標籤把所有子元素包裹在裏面。 如果刪除 divJSX 將不會編譯這些元素。 請記住這一點,因爲在 React 組件中返回 JSX 元素時也適用。

--hints--

常量 JSX 應該返回一個 div 元素。

assert(JSX.type === 'div');

div 應該包含一個 h1 標籤作爲第一個元素。

assert(JSX.props.children[0].type === 'h1');

div應該包含一個p標籤作爲第二個元素。

assert(JSX.props.children[1].type === 'p');

div 應該包含一個 ul 標籤作爲第三個元素。

assert(JSX.props.children[2].type === 'ul');

ul 應該包含三個 li 元素。

assert(
  JSX.props.children
    .filter((ele) => ele.type === 'ul')[0]
    .props.children.filter((ele) => ele.type === 'li').length === 3
);

--seed--

--after-user-code--

ReactDOM.render(JSX, document.getElementById('root'))

--seed-contents--


--solutions--

const JSX = (
<div>
  <h1>Hello JSX!</h1>
  <p>Some info</p>
  <ul>
    <li>An item</li>
    <li>Another item</li>
    <li>A third item</li>
  </ul>
</div>);
