Description

After creating an action, the next step is sending the action to the Redux store so it can update its state. In Redux, you define action creators to accomplish this. An action creator is simply a JavaScript function that returns an action. In other words, action creators create objects that represent action events.

Instructions

Define a function named actionCreator() that returns the action object when called.

Tests

tests:
  - text: The function <code>actionCreator</code> should exist.
    testString: 'assert(typeof actionCreator === ''function'', ''The function <code>actionCreator</code> should exist.'');'
  - text: Running the <code>actionCreator</code> function should return the action object.
    testString: 'assert(typeof action === ''object'', ''Running the <code>actionCreator</code> function should return the action object.'');'
  - text: The returned action should have a key property type with value <code>LOGIN</code>.
    testString: 'assert(action.type === ''LOGIN'', ''The returned action should have a key property type with value <code>LOGIN</code>.'');'
