--description--
在 React 中,設置默認的 props 是一個很有用的特性, 顯式設置組件的 prop 值即可覆蓋默認 props。
--instructions--
ShoppingCart 組件現在渲染了一個子組件 Items。 該 Items 組件有一個默認 quantity prop,其值被設置爲整數 0。 通過傳入數值 10 來覆蓋 quantity 的默認 prop。
注意: 請記住,向組件添加 prop 的語法與添加 HTML 屬性類似。 但是,由於 quantity 的值是整數,所以它不會加引號,但應該用花括號括起來, 例如{100}。 這個語法告訴 JSX 直接將花括號中的值解釋爲 JavaScript。
--hints--
應該渲染 ShoppingCart 組件。
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ShoppingCart));
    return mockedComponent.find('ShoppingCart').length === 1;
  })()
);
應該渲染 Items 組件。
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ShoppingCart));
    return mockedComponent.find('Items').length === 1;
  })()
);
Items 組件應該有一個 { quantity: 10 } 的 prop,該 prop 是從 ShoppingCart 組件傳遞過去的。
(getUserInput) =>
  assert(
    (function () {
      const mockedComponent = Enzyme.mount(React.createElement(ShoppingCart));
      return (
        mockedComponent.find('Items').props().quantity == 10 &&
        getUserInput('index')
          .replace(/ /g, '')
          .includes('<Itemsquantity={10}/>')
      );
    })()
  );
--seed--
--after-user-code--
ReactDOM.render(<ShoppingCart />, document.getElementById('root'))
--seed-contents--
const Items = (props) => {
  return <h1>Current Quantity of Items in Cart: {props.quantity}</h1>
}
Items.defaultProps = {
  quantity: 0
}
class ShoppingCart extends React.Component {
  constructor(props) {
    super(props);
  }
  render() {
    { /* Change code below this line */ }
    return <Items />
    { /* Change code above this line */ }
