why name: action.name?

Hellooo :)

I'm a beginner of React. And I'd like to know why we use {name: action.name} as the new state while adding new player instead of using {name:name} ?

Hi Jonus Wu, As we're only provided the state and action objects as arguments for our reducers, we have to extract the player name from the action item (which we haven't seen yet). That player name is stored in the action object under the key name, so action.name is appropriate. The variable name is not defined in the scope of our function.
