* 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.

5a24c314108439a4d403614d 定義一個 Redux Action 6 301440 define-a-redux-action

--description--

由於 Redux 是一個狀態管理框架,因此更新狀態是其核心任務之一。 在 Redux 中,所有狀態更新都由 dispatch action 觸發, action 只是一個 JavaScript 對象,其中包含有關已發生的 action 事件的信息。 Redux store 接收這些 action 對象,然後更新相應的狀態。 有時Redux action 也會攜帶一些數據。 例如,在用戶登錄後攜帶用戶名, 雖然數據是可選的,但 action 必須帶有 type 屬性,該屬性表示此 action 的類型。

我們可以將 Redux action 視爲信使,將有關應用程序中發生的事件信息提供給 Redux store 然後 store 根據發生的 action 進行狀態的更新。

--instructions--

編寫 Redux action 就像聲明具有 type 屬性的對象一樣簡單, 聲明一個對象 action 併爲它設置一個屬性 type,並將它的值設置成字符串'LOGIN'

--hints--

action 對象應該存在。

assert(
  (function () {
    return typeof action === 'object';
  })()
);

action 對象應該有一個值爲 LOGINtype 屬性。

assert(
  (function () {
    return action.type === 'LOGIN';
  })()
);

--seed--

--seed-contents--

// Define an action here:

--solutions--

const action = {
  type: 'LOGIN'
}
