* chore: rename APIs and Microservices to include "Backend" (#42515) * fix typo * fix typo * undo change * Corrected grammar mistake Corrected a grammar mistake by removing a comma. * change APIs and Microservices cert title * update title * Change APIs and Microservices certi title * Update translations.json * update title * feat(curriculum): rename apis and microservices cert * rename folder structure * rename certificate * rename learn Markdown * apis-and-microservices -> back-end-development-and-apis * update backend meta * update i18n langs and cypress test Co-authored-by: Shaun Hamilton <shauhami020@gmail.com> * fix: add development to front-end libraries (#42512) * fix: added-the-word-Development-to-front-end-libraries * fix/added-the-word-Development-to-front-end-libraries * fix/added-word-development-to-front-end-libraries-in-other-related-files * fix/added-the-word-Development-to-front-end-and-all-related-files * fix/removed-typos-from-last-commit-in-index.md * fix/reverted-changes-that-i-made-to-dependecies * fix/removed xvfg * fix/reverted changes that i made to package.json * remove unwanted changes * front-end-development-libraries changes * rename backend certSlug and README * update i18n folder names and keys * test: add legacy path redirect tests This uses serve.json from the client-config repo, since we currently use that in production * fix: create public dir before moving serve.json * fix: add missing script * refactor: collect redirect tests * test: convert to cy.location for stricter tests * rename certificate folder to 00-certificates * change crowdin config to recognise new certificates location * allow translations to be used Co-authored-by: Nicholas Carrigan (he/him) <nhcarrigan@gmail.com> * 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. >:( >:( >:( >:( Co-authored-by: Sujal Gupta <55016909+heysujal@users.noreply.github.com> Co-authored-by: Noor Fakhry <65724923+NoorFakhry@users.noreply.github.com> Co-authored-by: Oliver Eyton-Williams <ojeytonwilliams@gmail.com> Co-authored-by: Nicholas Carrigan (he/him) <nhcarrigan@gmail.com>

--description--
上一个挑战显示了组合两个组件的简单方法,但是有许多不同的方法可以把 React 组件组合在一起。
组件组合是 React 的强大功能之一。 当使用 React 时,应当先用组件的思路考虑清楚用户界面的结构(如上一个挑战中的 App 示例)。 可以将 UI 分解为基本的构建块,这些构建块就是组件。 这样做有助于将负责 UI 的代码与负责处理应用程序逻辑的代码分开, 并可以大大简化复杂项目的开发和维护。
--instructions--
代码编辑器中定义了两个功能组件,分别是 TypesOfFruit 和 Fruits。 请用组合或者嵌套把 TypesOfFruit 组件放到 Fruits 组件中, 然后把 Fruits 组件放到 TypesOfFood 组件中。 结果应该是子组件嵌套在父组件中,父组件嵌套在它本身的父组件中!
--hints--
TypesOfFood 组件应该返回单个 div 元素。
assert(Enzyme.shallow(React.createElement(TypesOfFood)).type() === 'div');
TypesOfFood 组件应该返回 Fruits 组件。
assert(
  Enzyme.shallow(React.createElement(TypesOfFood)).props().children[1].type
    .name === 'Fruits'
);
Fruits 组件应该返回 TypesOfFruit 组件。
assert(
  Enzyme.mount(React.createElement(TypesOfFood)).find('h2').html() ===
    '<h2>Fruits:</h2>'
);
TypesOfFruit 组件应该返回 h2 和 ul 元素。
assert(
  Enzyme.mount(React.createElement(TypesOfFood)).find('ul').text() ===
    'ApplesBlueberriesStrawberriesBananas'
);
--seed--
--after-user-code--
ReactDOM.render(<TypesOfFood />, document.getElementById('root'))
